What is Mabal?
Mabal is the dried, mature fruiting body of the giant puffball mushroom, used in Korean herbal medicine mainly for a sore, hoarse throat and to stop small surface bleeds. The Latin names are Calvatia gigantea and Lasiosphaera fenzlii. In English it is simply called puffball.
A mature puffball is a ball of fine brown spore dust (the powder the mushroom releases when it splits open). Practitioners use that powder in a gargle, blow it into the throat, or dust it onto a shallow cut or nosebleed. It is a single herb, not a formula.
Honest verdict up front: there are no published human trials of Mabal for any use. What exists is long traditional standing plus laboratory and animal work. Traditional use tells you what people have done for centuries; it is not proof that the remedy works, and that distinction applies to everything below.
How does Mabal work?
Nobody has shown how Mabal works in people. The ideas below are proposals from lab work, not proven mechanisms.
The spore powder is physically absorbent and slightly rough. When packed on a small cut it soaks up fluid and gives blood something to clot against, which is how many plant and fungal powders act as a styptic (something that helps stop bleeding).
Lab studies report that extracts slow the growth of some bacteria in a dish, and that mushroom beta-glucans (a type of sugar in fungal cell walls) can stir immune cells. Neither finding has been tested in a person with a sore throat.
What forms does Mabal come in?
Dried mature fruiting body, sold whole or in pieces by Korean and Chinese herbal pharmacies.
Loose spore powder, the most traditional form, used as a dusting powder or stirred into water.
A decoction (a tea made by simmering the herb), usually strained through cloth because the powder is irritating.
A gargle or throat wash made from that decoction.
Capsules and powders sold online, which are rarely tested for identity or metal content.
Where it comes from:
Mabal appears in classical East Asian materia medica and is recorded in Korean texts including the Donguibogam (1613), where it is used for swollen, painful throat, loss of voice, cough and bleeding wounds. The same drug is known as Mabo in Chinese practice.
Puffball spore dust was also used as a wound dressing in European and North American folk practice, which is why the traditional standing is wide rather than local. Its role has always been minor and symptomatic, never a central tonic.
If this is an emergency
Some reactions to Mabal need urgent care. Call your local emergency number or go to an emergency department straight away — do not wait to see whether it passes.
Who should avoid Mabal?
- Never collect wild puffballs yourself to use as medicine: the young button stage of deadly Amanita mushrooms looks like a puffball, and that mistake has killed people. Buy from a licensed herbal pharmacy.
- Do not use if you have asthma (a condition that narrows the airways), COPD (a long-term lung disease that makes breathing hard) or any other long-term lung condition — do not handle the spore powder at all.
- Do not breathe in the spore powder, and never let a child play with or crush a puffball.
- Do not use if you are pregnant or breastfeeding, because safety has not been studied.
- Do not give it to children.
- Do not use if you take immunosuppressant medicines (drugs that damp down the immune system), including after an organ transplant.
- Do not use if you are allergic to mushrooms or moulds.
- Do not pack the powder into a deep, dirty or bleeding-heavily wound, or into a surgical wound.
- Do not use it instead of antibiotics prescribed for a throat infection, and do not use it to delay seeing a doctor.
- Do not use products of unknown origin, as puffballs can take up heavy metals such as lead and cadmium from polluted ground.
When should you see a doctor?
Get emergency help if you have trouble breathing, chest tightness, swelling of the face, lips or tongue, or if you cannot swallow your own saliva.
Go to hospital straight away if you or a child has breathed in a cloud of spore dust and then develops cough, fever or breathlessness, even a day or two later. Say what happened, because this lung reaction is easily mistaken for ordinary pneumonia.
Call emergency services if anyone has eaten a wild mushroom that might not have been a puffball. Take the remains of the mushroom with you if you can.
See your doctor within a day or two if your sore throat comes with a high fever, lasts more than a week, or keeps coming back. Book an appointment if hoarseness lasts more than three weeks, if a nosebleed will not stop after 20 minutes of firm pressure, or if a wound becomes red, hot or swollen.
