This is an example of a formula that was designed on the basis of a survey of formulations used for a specific disorder category. The primary topic of the survey was treatment of psoriasis, though the same herbs are often used to treat eczema. To design the formula, the first step was to conduct an extensive review of the literature. This included books and medical journals published in China. Commonly used ingredients were identified, as were rarely used ingredients.
Some ingredients in the published formulas may be items favoured by the individual hysician or items that were given to address a particular symptom and/or pattern of signs that the physician descerned as being common (which might be different that the symptom and pattern of signs discerned by another physician). Other ingredients of the formula are those that are frequently mentioned in the traditional literature and/or in the modern literature as suitable for the disease.
Recognising the inherent diversity in formulas claimed to be of benefit, the formulas found in the literature are examined for the commonly used ingredients. Those that seem unusual, applied by only one physician and no others, and those that address symptom/sign patterns that might not be observed very often, are removed from consideration, as are any toxic ingredients. The resulting formula contains ingredients that are easily recognised by those who have a basic training in Chinese herbs.
The selected ingredients are then organised along the lines of well-known traditional formulas and modern clinical formulas of similar nature. Thus, Kochia 13 contains 7 ingredients of a published formula, Danggui Wume Tang (Tang Kuei and Mume Combination), that had been shown effective in a clinical trial, and 5 ingredients (mostly the sam as those in Danggui Wume Tang) of a traditional formula that has been widely used for skin ailments: Tang kuei and Arctium Formula (Xiaofeng San). The remaining ingredients of Kochia 13 are found in several of the other published prescriptions. The formulation was then orgaised to reflect the characteristics of the selected prescriptions. Most practitioners of traditional Chinese medicine would be expected to recognise the new formula as being similar to other treatments for psoriasis and eczema that are found in standard texts and, especially, in Chinese medical books about dermatology.
