Traditional Chinese medicine and psoriasis
What is psoriasis?
Psoriasis is a commonly seen chronic and inflammatory skin condition that results in red, thickened, flaky patches of skin covered with silvery scales. It may also be painful and, or itchy. It can occur on different areas of the body, but is commonly it is seen on the elbows, knees, and scalp. Psoriasis can also affect the nails, nail psoriasis, or the joints known as psoriatic arthritis.
It can affect people of any age. It is most commonly seen in those aged between 11 and 50 and can affect men and women equally. The condition is not infectious, nor is it contagious.
What causes psoriasis?
In biomedicine, the exact cause of psoriasis is not known. However, it is generally accepted that it is a kind of over activity of the immune system and possible inherited factors. These trigger the skin to produce new skin cells at a faster rate than normal. The skin cells are created and then die in the space of a few days, rather than the normal of 28 days. The dead skin cells build up on the surface of the skin, leading to thickening of the skin and shedding as scales.
Aggravating factors may include:
- Infections – some bacterial, fungal or viral infections
- Injuries or trauma to the skin – operations, bites, cuts, abrasions and severe sunburn.
- Certain medicines
- Stress and anxiety
- Alcohol, smoking, other recreational drugs
- Some food additives and preservatives, chemicals in cleaning products, paint, upholstery etc
What are the common types of psoriasis?
There are several types of psoriasis. They may occur singly or together.
- Plaque psoriasis (psoriasis vulgaris) – is the most common form of psoriasis. It is characterised by raised, inflamed, red lesions covered by a silvery white scale which can be itchy and sore. It can appear anywhere on the body but is typically found on the elbows, knees, scalp and lower back.
- Guttate psoriasis – commonly starts in childhood or young adulthood, often following an infection. It is characterised by small, red, individual spots on the skin. It usually appears on the trunk and limbs, with quick onset. May resolve by itself or develop into plaque psoriasis.
- Flexural (inverse) psoriasis – affects areas of the skin in folds or creases, such as elbows, knees the armpits, under the breasts, groin and between the buttocks. Bright-red lesions that are smooth and shiny, and often tender and itchy. It is often aggravated by rubbing and sweating and can be worse in hot and humid weather.
- Scalp psoriasis – occurs in small areas or the entire scalp. Red patches with thick silvery white scales characterise it. It can be intensely itchy. It may cause temporary hair loss.
- Nail psoriasis – affects the nails, causing them to develop tiny dents or pits, become discoloured, loose, even crumble or separate from the nail bed.
- Pustular psoriasis – an uncommon type of psoriasis. It begins with the reddening of the skin followed by the formation of pustules. They can be very painful and itchy.
- Erythrodermic psoriasis – a rare type of psoriasis that affects most of the skin. Periodic and widespread fiery redness and intense itching of the skin, and shedding characterise it.
- Psoriatic Arthritis – a small percentage of people with psoriasis also develop psoriatic arthritis. Commonly there is pain, stiffness and swelling in and around the joints. Joints commonly involved include the last joint in the fingers or toes, wrists, knees, ankles or sacrum.
Are there any biomedical treatments for psoriasis?
There is no cure for psoriasis in biomedicine. Treatments aim to manage the condition by clearing or reducing the patches of psoriasis. Various treatments are available for psoriasis, depending on the type, severity, and area of the skin affected.
Common treatments include:
- Topical treatment - creams, ointments, and moisturising preparations.
- Phototherapy - where the affected skin is exposed to ultraviolet light.
- Medication - to reduce the production of skin cells, or to treat the immune system.
Medications may have side effects. Over time, the skin can become resistant to treatment. Different types of treatment may be used in combination.

Treatment of psoriasis with traditional Chinese medicine
We conduct a skin examination, ask questions and conduct a traditional diagnosis to determine treatment. Following that, regular acupuncture is important. Usually once a week, sometimes more during a flare up, is recommended.
Chinese herbal medicine is essential. The strongest and most flexible way to administer them is to cook up the plant material as tea and to have a cup morning and evening. This way we can write a prescription that addresses the most pressing symptoms and the underlying factors. It is often necessary to continue the herbal medicine for several months. Sometimes we use herbal washes, soaps or ointments as well.
We may also suggest some lifestyle and diet changes as part of treatment.
Our experience is that psoriasis is well treated with traditional Chinese medicine . We also see an improvement in general health. Often as lesions clear there is no resulting scarring or skin discoloration.
