Zhu Ling猪苓
Polyporus · Polyporus Sclerotium · Umbellate Pore Fungus
Overview
A dark, knobbly fungus that grows on the roots of birch and maple — the plainest of the damp-drainers and the most single-minded. Sweet, bland and neutral, it does one thing: it promotes urination and moves standing water out of the body. It drains more strongly than Fu Ling 茯苓 but has none of Fu Ling's ability to strengthen the Spleen or settle the spirit, so it is almost always used inside a formula rather than on its own.

Cautions
It drains and does nothing else: with no damp to remove it simply depletes fluids, and prolonged or heavy use leaves the mouth dry and the person weakened. Not for someone without damp accumulation, and not appropriate where urination is already frequent and copious. Keep to the practitioner's amount and do not exceed 12 g a day. Anyone taking diuretic medication should tell the prescriber that this herb is in the formula.
Contraindicated in pregnancy: No specific restriction — practitioner judgment applies; used as a short course rather than continuously.
