Hanbang and Traditional Korean Skincare

Introduction to Hanbang Skincare

Hanbang skincare is a particular branch of Korean skincare that involves the use of herbal prescriptions and formulation techniques based on original principles of Traditional Korean Medicine (TKM) with incorporation of modern science.

This article wants to be a comprehensive introduction to the characteristics of Hanbang skincare and the principles behind it.

Disclaimer: I have personally translated the information and details in this article from original Korean sources, so I kindly ask you to credit my work if you intend to utilise any of the information provided in this guide.

Part 1: Hanbang Skincare

The History of Whoo - Gong Jin Hyang

1.1 Characteristics of Hanbang cosmetics

The official guidelines for labeling and advertising of Hanbang cosmetic products provided by the Korean government, define Hanbang cosmetics as:

While standard cosmetics are designed to treat specific skin concerns over a short period of time, the primary goal of Hanbang cosmetics is to boost skin’s self-resilience and enhance skin’s self-recovery power using the principles of Traditional Korean Medicine (TKM).

In Traditional Korean Medicine, pathological conditions and health concerns are considered consequences of weakened body’s immunity. For instance, when a healthy body is exposed to the flu virus, its immune system will be strong enough to prevent the body from getting sick. On the other hand, a weak immune system is more vulnerable to disease and infection.

Hanbang Skincare

Likewise, Traditional Korean Medicine sees skin concerns as signs of a physiological disharmony of the body. The primary goal of Hanbang skincare, which is based on the principles of TKM, is not treating specific skin concerns, rather harmonise the body to strengthen its immune defenses. In particular, Hanbang skincare has two main functions:

  • Rebalance yin and yang within the skin to enhance skin health.
  • Stimulate the flow of Qi and in turn, circulation of blood. In TKM Qi is the fundamental vital force that flows through all living things. When Qi doesn’t flow smoothly as it should, the stagnation leads to slowing of blood circulation, dull complexion, loss of elasticity and extreme dryness (in TKM, yin deficiency)2.

Unlike standard cosmetics, Hanbang skincare products are not classified by skin type. Rather, they aim to provide holistic care based on patterns of imbalances identified through TKM principles. Since Hanbang cosmetics mainly work on skin resilience, their main application lies in anti-aging skincare. In particular, the anti-aging lines of Hanbang skincare brands are based on the theory of aging and life cycles explained later in this article. Anecdotally, Hanbang skincare lines for very mature skin tend to be oilier than the ones for young skin so oily/combination skin types should keep that in mind.

1.2 Differences between Hanbang and standard cosmetics

In a 2011 report published on the academic journal NICE (News & Information for Chemical Engineers), a researcher from the Amorepacific “Korean Medicine Beauty Research Centre” summarised the key differences between Hanbang and standard cosmetics3.

1.3 Korean cosmetic regulations on Hanbang cosmetics

Despite being inspired by the principles and therapeutic prescriptions of Traditional Korean Medicine, from a legal standpoint Hanbang cosmetics are not considered any different from general cosmetics in Korea.

In 2012 the Korean Ministry of Food and Drug Safety issued guidelines for labeling and advertising of Hanbang cosmetic products1. The guidelines give a definition of Hanbang cosmetics and stipulate that, in order for a cosmetic to be marketed as “Hanbang”, it should contain at least 1% of Hanbang herbs (1g for every 100g/100ml) and it should comply with the safety standards set by the “Standards and Test Methods for Residues and Pollutants in Herbal Medicines”.

1.4 Chinese labelling regulations of Korean Hanbang cosmetics

On 14 December 2018, the Shanghai FDA (SHFDA) banned the use of the word “Hanbang”, either in Korean (한방) or Chinese language (韩方), on the packaging of Korean cosmetic products sold in China. The ban was later extended to the rest of the country. The Chinese health authorities argued that the word “Hanbang” could lead consumers to mistake these  cosmetics for drugs, since the word ‘bang’ (in Korean “방”, in Chinese “方”) translates to “medicine” in Chinese 4.

Following this decision, and considering China is the main foreign market for these products, many Korean beauty brands decided to remove any reference to “Hanbang” from the packaging of their products.

1.5 Efficacy of Hanbang cosmetics

Some Hanbang cosmetics with particular functions are recognised and regulated as “functional cosmetics” (기능성화장품). Article 2 of the Korean Cosmetics Act5 defines “functional cosmetics” as products that aid in functionally improving or changing  the condition of skin or hair. As of 2021, the Korean law identifies 11 categories of functional cosmetics6:

  • Cosmetic products that exhibit efficacy in promoting skin whitening by inhibiting the formation of blemishes, freckles, and other skin discolorations through the prevention of melanin pigmentation (“Whitening”).
  • Cosmetic products that exhibit efficacy in promoting skin whitening by diminishing melanin pigmentation in the skin (“Whitening”).
  • Cosmetic products that exhibit efficacy in smoothing or improving skin wrinkles by firming the skin (“Anti-wrinkle”).
  • Cosmetic products that exhibit efficacy in gently tanning the skin by screening strong sunlight (“UV-Protecting”).
  • Cosmetic products that exhibit efficacy in protecting the skin from ultraviolet rays by intercepting or scattering them (“UV-Protecting”).
  • Cosmetic products that exhibit efficacy in altering the colour of hair, including hair-decolourant products and bleaching agents. Products that provide only temporary hair colour changes are excluded.
  • Cosmetic products that exhibit efficacy in removing body hair. Products that involve manual removal of body hair are excluded.
  • Cosmetic products that exhibit efficacy in alleviating hair loss. Products that solely provide the appearance of thicker hair, such as coating products, are excluded.
  • Cosmetic products that have efficacy in relieving acne-prone skin (only rinse-off products).
  • Cosmetic products that exhibit efficacy in restoring the skin barrier function to alleviate skin itching.
  • Cosmetic products that exhibit efficacy in reducing the appearance of red lines caused by stretch marks.

Marketing claims related to functional cosmetics (i.e. whitening, anti-wrinkle) are strictly regulated and subject to a complex system of evaluation and pre-market approval by the Ministry of Food and Drug Safety (MFDS). Brands that want to use regulated functional claims to promote their products, must submit to the MFDS documentation that shows the safety and clinical effectiveness of the products before market release. The clinical effectiveness must be evaluated by independent testing agencies appointed by the government, which operate by following standards based on modern science.

Hanbang and Traditional Korean Skincare

In accordance with Korean cosmetic labeling requirements, when a cosmetic product is approved as a functional cosmetic, the words “기능성화장품” (“functional cosmetics”) must be displayed on the packaging, and the information should also be included in online product pages7. This allows consumers to identify products that were legally approved to have functional effects.

1.6 Hanbang skincare product terminology

The names of Hanbang skincare products frequently incorporate traditional terminology rooted in the principles of Traditional Korean Medicine, which may lack direct translations in English. Below is a list of the most common terminology used in Hanbang skincare and their correspondent English translations.

Hanbang Skincare

Literally “Nourishing Water”. Usually translated as “Balancer”, “Softener” or “Toner”. i.e. the original name of Sooryehan’s Hyobidam Fermented Toner is “Hyobidam Balhyo Soo Ek” (효비담 발효 수액) .

Hanbang Skincare

Literally “Nourishing Milk”. Usually translated as “Emulsion” or “Lotion”. i.e. the original name of Donginbi’s Red Ginseng Moisture & Balancing Emulsion is “Yoon Yoo Ek” (윤 유액).

Hanbang Skincare

Literally “Concentrated Fluid”/ “Essence” . Usually translated as “Essence”, Serum” or “Concentrate”. i.e. the original name of Yehwadam’s Hwansaenggo Ultimate Rejuvenating Serum is “Hwansaengoo Boyoon Jin Ek” (환생고 보윤 진액).

1.7 Popularity of Hanbang skincare

Although historical documents show that the topical use of medicinal herbs in Korea can be traced back to the Goryeo dynasty (918), the application of Traditional Korean Medicine principles to mass-produced skincare products is a fairly recent phenomenon.

The first Hanbang skincare brand in the history of Korean beauty dates back to 1973, when the Amorepacific Group (then called “Pacific Group”, 태평양) launched “Ginseng SAMMI” (진생삼미) a beauty brand formulated using ginseng saponin ingredients8.

The brand was exported to 34 countries and recorded 20 million dollars in sales, drawing more attention abroad than in Korea where ginseng was perceived as an expensive herb9.

In 1980 Jung San Biotechnology (정산생명공학), a company of herbal health supplements tried to replicate this success with the launch of a beauty brand called “Baekoksaeng” (백옥생)8 , but it wasn’t until 1997 that Hanbang skincare gained recognition with the Korean general public. 

In 1997 Amorepacific relaunched their iconic Hanbang brand under the name “Sulwhasoo“, with new products developed based on their extensive research of Traditional Korean Medicine prescriptions and skin aging. The new brand became an instant success with Korean consumers, surpassing 134 million dollars in sales within the first three years8.

This, along with the great popularity of historical television series centered around Korean medicine like  “Dae Jang Geum”, inspired many other companies like LG Household & Health Care, Coreana Cosmetics and Missha to launch Hanbang beauty brands in the early 2000s8.

Missha Hanbang 2015

By 2006 the domestic Hanbang skincare market was estimated to be worth 780 billion Korean won (around USD 655 million), with a growth rate of over 10% per year10.

Nowadays, Hanbang skincare is mostly popular among 30+ Korean consumers11 and Chinese consumers of all ages. In particular, the Chinese market for Korean Hanbang cosmetics was valued at 3.4 trillion Korean won (around USD 3 billion) in 201912 with names like LG’s “The History of Whoo” outperforming brands like Shiseido and La Mer13

1.8 Beauty companies with research centres dedicated to Hanbang

  • LG Household & Health Care: Whoo Oriental Medicine Skin Science Research Centre (후 한방 피부과학연구소). First Hanbang skin research centre in Korea14. In 2020 LG also acquired OBM Labs, one of the largest suppliers of Hanbang herbs15.
  • Amorepacific Group: Sulwhasoo Heritage & Science Center (SHSC) (설화수 한방과학 연구 센터). Formerly known as Korean Medicine Beauty Research Centre (한방미용연구센터).
  • Kolmar Korea: Ochang Skin Science Research Institute (오창연구소를).

Part 2: The Basics of Traditional Korean Medicine

Traditional Korean Medicine (TKM) is a form of oriental medicine based on medical practices originated in Korea. Like all branches of Oriental Medicine, TKM shares the same theoretical background with Traditional Chinese Medicine (TCM), but in time Chinese medicine was adapted to the Korean environment and culture and Korean Medicine became a distinctive regional tradition, with medical theories and therapies that are unique to Korea.

Similarly to TCM, Traditional Korean Medicine is a holistic medical practice that views the human body as a balanced network of interconnected systems, rather than as a collection of organs to be treated individually. When this balance is broken, the whole system is affected and illness arises. These imbalances are commonly attributed to external, internal or lifestyle factors and the goal of TKM is to preserve or restore the body’s natural equilibrium.

Hanbang

The theoretical framework of Oriental Medicine is based on philosophical beliefs originating from the observation of natural phenomena and the way individuals reflect and are affected by natural processes. A good example is the concept of Yin and Yang: Oriental Medicine observes that everything in nature is made of two opposite elements (i.e. dark/light, cold/heat etc) so humans, which are part of the natural world, are also believed to reflect this duality in their bodies.

Since these abstract concepts cannot be proven using methods accepted by modern science, Oriental Medicine is commonly classified as a form of complimentary and alternative medicine (CAM).

Although the mechanism of action of TKM therapies is not clearly understood from a modern scientific perspective, we do know that some of these therapies produce clinically observable results. Perhaps the most notable example is the 2015 Nobel-Prize-winning research on Artemisinin and its application in malaria treatment.

Nobel prize

In Korea, Traditional Korean Medicine is considered a valid healthcare system. Studies reveal that modern medicine is overall used the most, especially for complex and serious health conditions, but some categories of chronic diseases are more commonly treated using TKM therapies16.

Since the approval of the National Medical Act in 1951, South Korea recognises Korean medicine as legally equivalent to Western medicine, in what is commonly referred to as “a dual healthcare system”. In Korea therapies based on Traditional Medicine are covered by national health insurance and TKM medicines can be easily purchased from regular pharmacies.

Korean herbal medicine prescriptions are regulated and standardised as part of the Korean “Pharmaceutical Affairs Act”, the “Korean Pharmacopoeia” (KP), the “Korean Herbal Pharmacopoeia” (KHP) and their related enforcement rules, and the profession of Korean Medicine practitioner is regulated by the “Medical Service Act”. While there are still many challenges before TKM becomes internationally recognised an evidence-based science, the industry is certainly not as unregulated as some Western media outlets suggest and South Korea is making significant efforts to standardise and regulate the practice.

Furthermore, Korean national institutions are actively promoting the integration of modern healthcare and traditional medicine through bills like the 2013 “Oriental Medicine Promotion Act”, an act meant to support the standardisation and advancement of TKM practices by modern scientific standards through financial support of research and specialised institutions17.

A particularly meaningful initiative is the foundation of the Korea Institute of Oriental Medicine, a government-funded research institute with the goal of researching and standardising Oriental Medicine therapies using modern scientific standards and technology. The institute is also responsible for publishing “Integrative Medicine Research“, a quarterly, single-blind peer-reviewed, open access journal focused on evidence-based scientific research in integrative medicine, traditional medicine, and complementary and alternative medicine18

2.2 Key principles of Traditional Korean Medicine

In Oriental Medicine, Qi represents the intangible vital energy that runs through all living things, including the human body. In the body, it’s believed that Qi is essential to maintain a person’s health. It’s the vital force that powers the physiological functions of all organs and protects the body from external pathogens.

Diseases  and health conditions are interpreted to be the result of Qi imbalances (i.e. stagnation, deficiency etc).

Note that in Traditional Chinese Medicine this word is also romanised as “Qi”, but pronounced “Chee” (氣), while in Traditional Korean Medicine it’s romanised and pronounced “Qi” (“기”).

Yin and Yang is a philosophical concept used to describe the duality of natural phenomena. Just like light and darkness, hot and cold, happiness and sadness etc. everything in the universe exists as two opposing interdependent forces called “Yin” and “Yang”.

In Oriental Medicine, the parts and functions of the human body are also classified into “Yin” and “Yang” and health is defined as the dynamic equilibrium between these forces. Illness arises when this balance is disrupted, and TKM therapies aim to preserve or restore this delicate harmony.

The two main substances of the human body are also described in terms of Yin and Yang: Qi is Yang in nature (dynamic and transforming), while Blood (which is not to be interpreted in the Western anatomical sense) is described as a denser form of Qi and is Yin in nature (fluid and substantial). Since they have a Yin and Yang relationship, Qi and Blood are mutually dependent. Qi produces and circulates Blood throughout the body, while Blood nurtures and maintains the Qi. This relationship is described in classic literature as “Qi is the commander of Blood and Blood is the mother of Qi“.

In Oriental Medicine, meridians (in Korean 경락, “Kyeong-rak”) are considered the pathways through which the vital energy Qi flows and is distributed across the body. Disturbances and blockages in these channels are believed to lead to Qi stagnation and disease.

The Five Phases is the philosophical notion that all changes in the universe happen in a pattern of five stages. The five stages correspond to five natural elements: 

  • Wood (birth)
  • Fire (growth)
  • Earth (maturation)
  • Metal (death)
  • Water (rebirth)

As part of nature, the internal organs of the human body are also believed to correlate with the Five Phases according to their behavior and function in the body.

  • Wood > Liver (liver spreads Qi across the body like branches of a tree)
  • Fire > Heart (Heart governs the blood which is red like fire)
  • Earth > Spleen (Spleen digests food harvested from earth)
  • Metal > Lungs (Lungs works to purfy and detoxify like pure metal)
  • Water > Kidney (the Kidney control body fluid)

There are two cycles of transformation that keep the five phases in equilibrium.

  • Mutual promotion (the first phase gives birth to the second): Earth > Metal > Wood > Fire >Earth
  • Mutual restriction (the first phase restrains the second): Earth > Water > Fire > Metal > Wood > Earth

These interactions are used in TKM to understand the cause of a disease and its treatment. i.e. if there is excess qi in the liver (liver qi stagnation), the spleen will be weakened since Wood (Liver) suppresses Earth (spleen), so an effective therapy would be to abate Wood (Liver) and support Earth (spleen) with remedies that have those properties (refer to the chapter “herb properties”).

The Five Elements Principle is referred to as “O Haeng” (오행) in Korean, and Wu Xing (五行) in Chinese. This principle and the colours associated with it are the inspiration behind “Obangsaek“, a palette of traditional colours that are ubiquitous in Korean culture25.

2.3 Aging in Oriental Medicine: the cycle theory

In Oriental Medicine, the aging process is considered the consequence of the progressive depletion of Jeong (essence). Note that, while in Korean essence is referred to as “Jeong” (정), in Chinese it’s called “Jing” (精).

According to this theory, each person has both a congenital essence (a fixed amount inheritated at birth from their parents) and an acquired essence obtained from food and drinks. Both types of essence are stored in the Kidney and they provide the energetic basis for growth, development and all living activities. It’s important to stress out that there is no correspondence between TKM organs and Western anatomy, so in this context Kidney is not to be intended in the anatomical sense.

When a person grows old, they gradually consume all their available essence until exhaustion, which coincides with death. Jeong (essence) and Qi (vital energy) have an interdependent yin/yang relationship: Jeong is the material basis of existence that is constantly transformed to release Qi, while Qi transforms food to nourish Jeong.

In particular, it’s believed that this depletion of Jeong (an in turn, Qi) develops following predictable periodical cycles (“life cycles”), where each cycle is defined by specific physiological changes and patterns.

The characteristics of each life cycle are described in the first chapter of the Hwangjenaegyeongsomun (in English “The Yellow Emperor’s Classic of Internal Medicine“), a Chinese medical text considered the foundation of Oriental Medicine.

In women:

There are 7 stages of a woman’s life, with each cycle changing at an interval of 7 years.

  • First cycle (age 7) – Kidney Qi becomes abundant, permanent teeth replace baby teeth and hair grows longer.
  • Second cycle (age 14) – The Ren meridian flows and the Chong meridian starts to fill with blood, leading to the onset of menstruation. The Chong meridian is believed to turn Qi into Blood and regulate the female reproductive system, while the Ren meridian (also known as the Conception meridian) plays an essential role in male and female fertility.
  • Third cycle (age 21) – Kidney Qi peaks, becoming balanced and stable, and body development stops.
  • Fourth cycle (age 28) – Bones, and reproductive organs reach their full development and the body is at optimal condition. The fourth cycle is considered the ideal time to have children.
  • Fifth cycle (age 35) – Body starts to gradually decline. The Large Intestine meridian (which distributes Qi and Blood to the skin) starts degenerating, which results in complexion losing its radiance, and the appearance of initial signs of aging (sallow face, wrinkles, hair loss).
  • Sixth cycle (age 42) – The three upper Yang meridians, responsible for distributing Qi and Blood in the upper body, begin to decline, leading to facial sagging and gradual whitening of hair.
  • Seventh cycle (age 49) – The Qi of the Ren meridian (responsible for conception) and the Chong meridian (responsible for menstruation and general regulation of the femal reproductive system) decline. Menstruation ceases and body becomes old and feeble.
In men:

There are 8 stages of a man’s life, with each cycle changing at an interval of 8 years.

  • First cycle (age 8) – Kidney Qi grows, permanent teeth replace baby teeth and hair grows longer.
  • Second cycle (age 16) – Kidney Qi becomes abundant, and he’s able to let sperm out.
  • Third cycle (age 24) – Kidney Qi peaks, body development stops.
  • Fourth cycle (age 32) – Body is fully developed and at optimal condition. Muscles and limbs are strong and sturdy.
  • Fifth cycle (age 40) – Kidney Qi begins to decline, which results in gradual hair loss and teeth withering.
  • Sixth cycle (age 48) – The body’s Yang energy starts degenerating, leading to facial sagging and gradual whitening of hair.
  • Seventh cycle (age 56) – Kidney Qi deficiency results in Liver decline. In Oriental Medicine Liver is the part of the body that governs tendons and regulates movement. Liver deficiency in the seventh cycle results in rigid tendons and joint problems.
  • Eight cycle (age 64) – Jeong and Qi are depleted, along with bones and tendons.  Teeth fall out and body becomes decrepit.

2.4 Classic texts of Korean Medicine

The “Regulation on Approval and Notification of Herbal (crude) Medicinal Preparations” (one of the Enforcement Rules of the Korean Pharmaceutical Affairs Act) recognises the validity of herbal medicinal preparations based on recipes found in 10 historical textbooks of Traditional Korean Medicine19. Herbal prescriptions that are not based on existing recipes found in these books, are subject to pre-market evaluation of clinical efficacy following modern scientific standards.

The books are:

  • Dongui Bogam (동의보감) – First published in 1613 and considered the most representative text of Traditional Korean Medicine.
  • Bangyakhapyeon (방약합편) – Published in 1884.
  • Hyangyakjipsungbang (향약집성방) – Published in 1433.
  • Kyungakjeonseo (경악전서) – Published in 1624.
  • Uihakipmun (의학입문) – Published around 1580.
  • Jaejungshinpyeong (제중신편) – Published in 1799.
  • Kwangjaebigeop (광제비급) – Published in 1790.
  • Donguisoosebowon (동의수세보원) – Published in 1901.
  • Bonchogangmok (본초강목) – Published in 1596.
  • Dongui Susebowon (동의수세보원 ) – Published in 1901.

Part 3: Hanbang Herbal Remedies and How They’re Formulated

Hanbang

In this section I’m going to analyse the defining characteristics of Hanbang herbs and the principles used to combine them to form Hanbang prescriptions (oral or topical).

3.1 Hanbang herbs

The Korean medicine codex, which consists of the Korean Pharmacopoeia (KP) and the Korean Herbal Pharmacopoeia (KHP), currently recognises 601 crude herbal substances24. The herbs are either:

  • Plant-based (roots, leaves, seeds, fruits, bark etc)
  • Mineral-based (gold, clay etc)
  • Animal-based (deer antlers, oyster shells etc)

The active principles and therapeutic effectiveness of herbal substances depends on a variety of factors, most notably: species, growing environment (quality of the soil, quality of water, climate, hours of sunshine etc), harvesting conditions (wild harvesting, natural foresting, cultivation, time of harvesting etc) and processing methods.

A prime example is Panax Ginseng, one of the most expensive Hanbang herbs. Not only wild ginseng and cultivated ginseng present significant morphological differences, but wild ginseng was also shown to contain at least 10 times the amount of active compounds of cultivated ginseng20. The different market price of the two varieties reflects their different effectiveness.

wild ginseng vs cultivated ginseng

In Oriental Medicine, “Daodi” is a term that indicates medicinal herbs with the highest pharmacological properties, grown in specific geographical areas with specific natural conditions and being harvested and processed following specific standards. In 2015 the Korean Institute of Oriental Medicine published a guide on Korean medicinal herbs, their varities, characteristics and original growing environment. The guide is available for free on the KIOM’s website (in Korean language).

3.2 Herb properties

Hanbang prescriptions usually consist of a complex combination of multiple herbs. The herbs used in the prescriptions are not meant to treat symptoms of diseases, like in Western herbology, but they’re selected to target precise patterns of disharmony in the body.

i.e. in the case of excessive sweating, the Western herbology approach is to directly target the main symptoms of the condition by using natural remedies like green tea that help constrict sweat glands. The Hanbang approach on the other hand, looks at the patterns associated with sweating (mainly: excessive body heat and leakage of fluid) and prescribes herbs to treat these patterns, even if they’re not directly linked to overactive sweat glands.

Each herb has a different nature and understanding the natural properties of herbs can help us understand what types of patterns each herb can treat.

Temperature:

The temperature of a herb is determined by observing the herb’s effect on the body (i.e. mint is considered a herb with a cool nature). Herbs are classified into:

  • Hot
  • Warm
  • Neutral / Balanced
  • Cool
  • Cold

Herbs with hot/warm properties can be used to treat conditions considered cool or cold in nature, and viceversa. Neutral herbs can be used to treat both cold and hot conditions. Treating hot with hot and cold with cold is strongly discouraged. 

Five Tastes / Flavours:

Herbs can have one or more tastes, based on their real mouth taste. Flavours are used to determine which action of effect a herb will have on the body.

Additional properties:
  • Bland (Tasteless): Substances that stimulate urination to remove dampness.
  • Aromatic: Substances that help open the orifices, awaken the spleen and clear dampness.
  • Astringent: Substances that arrest the abnormal leakage of qi like sour herbs, but they don’t have a sour taste.
Direction:

Lastly, some herbs have directional qualities that show the inclination and direction of their action. These properties are used to guide the therapeutic effect of the other herbs to a particular area in the body or counteract pathological actions that are moving in the opposite direction.

  • Ascending (moving upwards in the body): Light substances such as flowers and rapidly growing plants.
  • Descending (moving downwards in the body): Heavy salty substances like shells and minerals.
  • Floating (moving outwards in the body): Dispersing herbs that release the exterior.
  • Sinking (moving inwards in the body): Astringent herbs that bind and prevent leakage.

3.3 Herb preparation and processing methods

Along with the quality of raw materials, the effectiveness of Hanbang prescriptions depends on how the herbs used in these formulas are processed and extracted. In Oriental Medicine, processing methods are applied to raw herbal materials to accentuate or diminish particular properties of that herb for a specific therapeutic use. The correct preparation of its herbal components, insures the optimal effect of the final formula.

Traditional herbal processing methods are known as “Po Jae” (포제) in Korean and “Pao Zhi” (炮制) in Chinese, and they represent an integral aspect of Traditional Korean Medicine. The main objectives of the processing methods are:

  • Washing and removing impurities and foreign, non-medicinal substances
  • Eliminating toxicity and reducing side effects of the herb
  • Facilitating storage, medicinal production and assimilation
  • Increasing the therapeutic effects of the herb material
  • Altering the medicinal properties of the herb (flavour, nature, action etc)
  • Reducing unpleasant odours and tastes.

How different processing methods can affect the properties and uses of an herb. An example of the significance of processing methods comes again from Panax Ginseng.

There are many methods to process herbs before usage, with each option having distinctive effects on the benefits and usage of a certain herb. The choice of a particular processing method over another, as well as the specifications of the process (i.e. how long a material should be steamed), depend on the characteristics of the original material and the desired therapeutic effect.

Some of the most common processing methods used in Traditional Korean Medicine are outlined below. 

Basic preparation

Methods include: washing, pulverisation, slicing, cutting or defatting.

Processing herbs with the aid of water

Materials are treated with the aid of water or other liquids to eliminate impurities and refine the characteristics of the remedies. Methods include: rinsing and washing, moistening, soaking or aqueous trituration.

Processing herbs with the aid of fire

Materials are exposed directly or indirectly to fire until they become yellow, brown, carbonized or calcined. Methods include: stir-frying without excipients (dry-frying), stir-frying with excipients (solid or liquid), calcination, roasting, baking or blast-frying.

Processing herbs with the aid of water and fire

Materials are processed with the intervention of heat and certain liquids. Methods include: steaming, boiling, scalding, dip calcining or distilling.

Fermentation and Germination

Materials are exposed to a certain humidity and a certain temperature until they ferment or germinate.

3.4 Herbal compatibility and interactions

The use of individual herbs in Hanbang herbal prescriptions is rare, as they usually consist of a synergistic combination of multiple substances. These prescriptions are formulated in accordance with the principles of the “seven-relation compatibility”, a theory used to determine whether or not various herbs are compatible with each other and how they interact with each other.

3.5 Combining medicinal substances: the Gunsinjwasa (Jun-Chen-Zuo-Shi) principle

As mentioned, Hanbang prescriptions usually consist of a complex combination of multiple substances with different medicinal properties that work synergistically to provide treatment for a certain condition.
The synergistic interactions among the ingredients of a prescription are believed to boost the bioavailability of active components in the formula22. The concept of synergy is a key part of Oriental Medicine and it’s different from the concept of simple addition. In fact, synergy occurs when the combination of multiple components produces a total effect that is greater than the sum of its individual elements.

These synergistic formulas are constructed following the principle of “Gunsinjwasa” (“군신좌사”, from the Chinese “Jun-Chen-Zuo-Shi”, “君臣佐使”),  a complex hierarchy of actions and functions designed to target all aspects of a condition.

Some simple prescriptions can contain only the main principles (Gun Yak and Sin Yak) or a substance can serve more than one function within the same formula.

A 2015 study by a Korean research team led by Professor Lee Sang Yup from the Department of Chemical and Biomolecular Engineering at KAIST, found that not only prescriptions formulated following the Gunsinjwasa principle had a synergistic mechanism, but they also shared significant structural similarities to human metabolites, especially when compared to Western medicinal prescriptions23.

Below an example of the application of the Gunsinjwasa principle in the formula of a cosmetic product. In the picture the core formula for The History of Whoo’s Hwanyu line.
