Gui Zhi Fu Ling Wan (Cinnamon Twig and Poria Pill) guì zhī fú líng wán · 桂枝茯苓丸

Safety. There is a genuine tension in this formula that a reader should see rather than be shielded from. The classical text presents it in a pregnancy-related context, while modern practice generally treats blood-moving formulas as contraindicated in pregnancy. This site does not resolve that tension for the reader; it is exactly the sort of question that belongs with a qualified practitioner, and it is a reason not to self-administer this formula at all during pregnancy or suspected pregnancy. - 桃仁 (persica seed) contains amygdalin, a cyanogenic glycoside that can release cyanide in sufficient quantity - uncommon, but it is the reason the seed is not a food-like ingredient. - 桂枝 is cassia twig, and cassia cinnamon is the cinnamon chemotype notable for coumarin content; coumarin is hepatotoxic at sustained high intake and has anticoagulant properties, so the combination of liver disease and anticoagulant medication is where this matters. - 牡丹皮 (moutan bark) contains paeonol; it is another blood-moving component carrying the same pregnancy caution. - 芍药 deserves a specific note: the classical text simply says 芍药, and today 白芍 (white peony, with the bark removed and processed) and 赤芍 (red peony) are different articles with different traditional roles. Which one a manufacturer used changes the product, and this is a real ambiguity rather than a pedantic one. - The most common modern marketing of this formula is for uterine fibroids and ovarian cysts. What can be said honestly: the traditional indication is a pattern, not a diagnosed mass, and whether this formula reduces fibroid size or resolves cysts is not established. Presenting it as a way to avoid surgery is not supportable. - 茯苓 is generally well tolerated. - Amounts are set by a licensed practitioner and are deliberately not given here.
