To the Editor: Mr Bensoussan and colleagues1 summarized the 20 herbal ingredients in the standard
formula capsule in a table but did not identify the 81 Chinese herbs used
in the individualized treatment group. No specific dosage was listed except
for percentage in the standard formula and the number of capsules used.
The failure of accurate and full documentation of ingredients and dosage
in Chinese proprietary and herbal medicines is not uncommon.2
Misidentification of an herb3 was unlikely
in the study, although there was preparation of herbal powders from the plants,
introducing the possibility of inaccurate processing of ingredients.
