Phallus indusiatus is an edible mushroom, eaten mainly as food in China and South East Asia. Cooks know it as bamboo fungus, zhu sheng, or the veiled lady. It grows a white lacy net below the cap, which is how it got that last name.
It is sold dried, as whole stems or cut strips. People soak it, trim it, and drop it into soups, broths and hot pot. It has little flavour of its own and takes up the taste of the stock.
Some sellers also market it as a health supplement in powder or capsule form. Here is the honest verdict: human evidence for any health benefit is very thin. Long use in cooking is not proof that it treats anything, and it is not proof that strong extracts are safe.
No mechanism for this mushroom has been confirmed in people. What exists is laboratory and animal work, and that is a long way from a proven effect.
In test tubes, polysaccharides (large sugar molecules) from the mushroom appear to mop up free radicals. In cell studies, beta-glucans from many mushrooms seem to nudge immune cells into action. Whether eating the mushroom does this in your body has not been shown.
In mice, some extracts have been reported to lower markers of swelling and to shift gut bacteria. These are early animal findings. They do not tell you what a bowl of soup, or a capsule, will do for a person.
As a food it does one thing plainly: it adds fibre and bulk with very few calories. That is nutrition, not medicine.
You are most likely to meet it in these forms:
- Dried whole stems, sold in packets in Asian grocers. - Dried cut strips, ready to soak for soup. - Fresh, sold near where it is grown, which is rare outside Asia.
- Powder, sold as a food topping or in drink mixes. - Capsules and liquid extracts, sold as supplements.
The food forms have a long record of being eaten. Capsules and strong extracts are newer, and much less is known about them.
This mushroom was prized in Chinese cooking long before anyone studied it. Old records place it on imperial banquet tables, where it was treated as a delicacy rather than a drug.
Chinese food writing described it as a cooling and light food, suited to clear soups. Some later folk sources also linked it to energy and general strength. These were ideas from cuisine and custom, not from testing.
It has been farmed on a large scale in China since the late twentieth century. That is why dried packets are now cheap and easy to find.
Stop and get urgent medical help if you have swelling of the lips, face or throat, a widespread rash, or trouble breathing after eating it. These point to an allergic reaction.
See your doctor if you get stomach pain, vomiting or diarrhoea that does not settle within a day.
Also speak to your doctor before starting any mushroom supplement if you take a blood thinner (anticoagulant), diabetes medicine or cancer treatment.
In the United States, the European Union, the United Kingdom and Australia it is sold as an ordinary food. Capsules and powders are sold as food supplements, not as licensed medicines. No health claim for it has been approved by those regulators.
