• In general, the longer the patient has suffered from psoriasis the longer the length of treatment. Generally speaking, the course of treatment for the first and second types will be shorter than for the third type. Average courses of treatment for the different patterns are as follows:
i. Flaming of heat-evil at the qi and blood levels combined with wind: 2-3 months.
ii. Blood-heat and blood-stasis plus generalised symptoms: 3-4 months.
iii. Noxious-heat and blood-stasis: 4-6 months. ¥ Some patients have to continue treatment for longer, possible over a year, especially those who have had lengthy treatment with Western medicine such as steroids (tablets or creams), as the psoriatic lesions become very stubborn. If after a few weeks of treatment the symptoms start to improve, the patient may need to take the treatment consistently until it has cleared completely. ¥ If appropriate, it is possible to prescribe two of the three decoctions together by mixing a half dose of each, according to the principles of differential diagnosis. ¥ Some common difficulties that may present during treatment:
i. Plateau in recovery Initially the patient recovers, but after a few weeks or months this recovery ceases or the condition actually worsens. This can be treated by adding Wu Wei Xiaodu Yin (Antiphlogistic Decoction of Five Ingredients): Jin Yin Hua (Flos Lonicerae Japonicae) 12g Pu Gong Ying (Herba Taraxaci Mongolici cum Radice) 9g Ye Ju Hua (Flos Chrysanthemi Indici) 9g Zi Hua Di Ding (Herba Violae cum Radice) 9g Zi Bei Tian Kui (Herba Begonia Fibrislipulatae) 9g Most cases will recover again in one or two weeks. If necessary, change to another decoction or modify the original prescription according to a good differential diagnosis. ii. Relapse or recurrence Stress, overwork, seasonal changes, certain foods and
some infections are examples of common reasons for relapse or recurrence of psoriasis. It is necessary to ascertain the trigger(s) for the relapse and advise the patient accordingly. Wu Wei Xiaodu Yin or a prescription to drain dampness can be added, or alternatively acupuncture can be offered in addition to the herbal treatment. To deal with a recurrence, the prescription that the patient had during the last course of treatment prior to recovery should be selected. If this is successful after 710 days, the treatment should continue until full recovery occurs. If this prescription is not successful, Wu Wei Xiaodu Yin or a prescription to drain dampness, or a recipe to invigorate blood circulation and eliminate blood stasis can be added, or acupuncture may be applied. These will usually have a satisfactory result. Prevention ¥ Take enough rest, refrain from overworking and avoid too much mental stress. ¥ Try not to scratch the affected area. During onset, the affected area should be bathed in hot water or with alkali soap. ¥ Refrain from eating the following foodstuffs: seafood such as fish and shrimp, beef, lamb, spicy foods, alcohol and caffeinated drinks such as coffee, tea and coca-cola, as these are likely to induce or intensify psoriasis. ¥ Sound nutrition should be maintained. Eat more vegetables and fruit in order to keep the bowel movements regular. ¥ Try to trace any triggering factors and thereby reduce relapses.
