Contraindications

As with the parent formula, only for excess patterns. Not for the frail or elderly, not with a weak Spleen and loose stool, not in a deficiency fever. Note that some later transmissions of Yi Yuan San add cinnabar, a mercury mineral — that version is not used, and any product listing cinnabar should be refused.

For licensed practitioners’ reference only — not a self-treatment guide.

Pregnancy

Contraindicated in pregnancy — it carries the whole purging and sweating body of Fang Feng Tong Sheng San, including Da Huang, Mang Xiao and Ma Huang.
