Traditional Chinese Medicine

TCM Summary

Studies in Australia, Europe, and the United States have estimated that psoriasis is found in one to five percent of the general population.[1] Psoriasis is not only a skin disease and may also affect a person’s joints,[2] cardiovascular system,[3] and psychological state.[2,4,5]

In Traditional Chinese Medicine (TCM), psoriasis (白疕, bai bi or white mange), can develop from a number of underlying imbalances in the body. The main imbalances causing psoriasis are heat as well as the stasis of Qi and blood.[6,7]

Treatment Philosophy

TCM focuses on how psoriasis relates to lack the type and intensity of the heat causing the psoriasis. The goal of TCM therapy is to correct the underlying imbalance causing the psoriasis by removing heat, stimulating blood circulation and nourishing dryness.

Symptoms and Causes

Psoriasis is a chronic, inflammatory skin rash that can affect the skin, hair, and nails. It most commonly begins in adolescence and young adulthood but can occur at any age. It often appears as red skin plaques with silvery-white scales found on the body or scalp. The affected skin can itch, burn, become scaly, or have no associated symptoms at all. Less common forms of psoriasis can look like small scaly rain drops on the skin (guttate psoriasis), pus-filled bumps known as pustules (pustular psoriasis), scaling of only hands and feet (hand and foot psoriasis), and pitting or yellowing of the nails (nail psoriasis), to name a few. Beyond affecting skin, inflammation of the joints is a condition known as psoriatic arthritis. Psoriasis is thought to be due to an imbalance in the immune system that leads to areas of increased inflammation in the skin.

Chinese Herbs

Herbal medicine is the main therapy for psoriasis in TCM. Traditional Chinese Medicine doctors may write an herbal formula consisting of multiple herbs with a focus on resolving the underlying imbalance. Herbs can be prepared for external application or can be ingested internally.

Many Chinese herbs have been shown to reduce inflammation. Here is a profile of just a few common herbs used for different types of psoriasis:

  • For treating heat, the herbal formula will focus on herbs that are cooling. Sheng di huang (Rehmania glutinosa) and Zi cao (Lithospermum erythrohizon) are both cooling herbs that are central in the treatment of heat. These herbs have been shown to reduce the levels of the inflammatory cytokine TNF-α which is active in psoriasis.[9]
  • For addressing blood stagnation, the herbal formula will include herbs that stimulate the movement of blood and nourish the blood. Dan shen (Salvia miltiorriza) is known for moving and nourishing the blood. Dan shen has been shown to inhibit the secretion of inflammatory cytokines IFN-γ and IL-12 which are active in psoriasis.[9]
  • Licorice root, or gan cao (Glycyrrhiza uralensis), is widely used in Chinese medicine for all types of psoriasis, as it boosts Qi and harmonizes the effects of other herbs. It has long been known to reduce inflammation but also enhance the immune system. [9]

Diet and Lifestyle

Nutrition and diet

  • Diet: Diets high in processed fats and refined sugar also injure our digestive energy and lead to the development of dampness and heat. Chinese medicine recommends staying away from rich fatty foods, particularly some types of seafood, because they can lead to accumulation of heat in the body. Instead, eat fish rich in omega-3 fatty acids such as salmon and sardines. Focusing on a diet rich in omega-3 fatty acids has been suggested to help psoriasis.[10]
  • Alcohol: Consuming too much alcohol leads to the development of dampness and damp heat. It will injure the digestive energy impairing the body’s ability to maintain overall health.


  • Exercise: Exercise will help increase the circulation of Qi and relieve stress, and can lead to psoriasis improvement.
  • Stress reduction: Circulation and flow of Qi, our body’s energy, is imperative for a healthy life. Stress inhibits the flow of Qi leading to stagnation.
  • Smoking: Smoking has been associated with worsening of psoriasis.[11] Smoking adds heat to the body, which will exacerbate the underlying heat condition in psoriasis. s
