Herbs Traditionally Used for Edema
The Donguibogam view
The Donguibogam explains edema as the spleen, lung, and kidney together losing their grip on water metabolism — when the spleen cannot move water or the kidney cannot filter it, water accumulates in the body. Its herbs pair those that firm the surface with those that open internal water passages.
This page organizes herbs recorded in the Donguibogam's herbology volume for edema, with original citations. Edema can signal heart, kidney, or liver disease — please check the warning signs below first.
Herbal reference is not appropriate in these situations — seek medical care first:
- Sudden one-sided leg swelling with pain or warmth (possible blood clot — seek care immediately)
- Edema with difficulty breathing or chest pain
- Facial or eyelid swelling with foamy urine
- Rapidly worsening edema, or unexplained whole-body swelling
- Suddenly worsening edema during pregnancy

Frequently asked questions
Is astragalus used for edema too?
Yes. Tradition records astragalus as firming the exterior and promoting urination to reduce swelling, especially combined for edema from qi deficiency.
How do poria and alisma differ?
Both drain water, but poria does so gently while also calming the spirit — a balanced herb — while alisma acts more directly and strongly to expel water from the bladder.
If my legs swell often, can I just take diuretic herbs?
No. Sudden one-sided swelling or swelling with breathing difficulty or chest pain can signal heart or vascular disease, and medical care should come before any herbal reference.
