Overview Information

Shiitake mushroom is a fungus. An extract made from this mushroom is used as medicine.

Shiitake mushroom is used to boost the immune system and to treat HIV/AIDS, common cold, flu (influenza), and many other conditions, but there is no good scientific evidence to support these uses.

How does it work?

Shiitake mushroom contains chemicals that might stimulate the immune system.


Uses & Effectiveness?

Possibly Ineffective for

  • Tooth plaque. Rinsing the mouth with a liquid containing shiitake mushroom does not seem to reduce tooth plaque.

Insufficient Evidence for

More evidence is needed to rate the effectiveness of shiitake mushroom for these uses.

Side Effects

Side Effects & Safety

When taken by mouth: Shiitake mushroom is LIKELY SAFE when consumed in food amounts. It is POSSIBLY UNSAFE in medicinal amounts. It can cause stomach discomfort, blood abnormalities, and skin swelling (inflammation). It might also cause an increased sensitivity to the sun, allergic skin reactions, and breathing problems.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if shiitake mushroom is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.

"Auto-immune diseases" such as multiple sclerosis (MS), systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), or other conditions: Shiitake mushroom might cause the immune system to become more active. This could increase the symptoms of auto-immune diseases. If you have one of these conditions, it's best to avoid using shiitake mushroom.

A blood disorder called eosinophilia: Don't use shiitake mushroom if you have this condition. It might make eosinophilia worse.



We currently have no information for SHIITAKE MUSHROOM Interactions.



The appropriate dose of shiitake mushroom depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for shiitake mushroom. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
