Overview InformationAgaricus mushroom is a fungus. It originated in Brazil, but is now grown in China, Japan, Brazil, and the US. Solutions containing chemicals that are taken from the plant are used as medicine.
Agaricus mushroom is used for various types of cancer, and for the side effects of cancer treatments, but there is no strong evidence supporting any uses.
How does it work?Some developing research suggests agaricus mushroom might strengthen the immune system, fight tumor development, and work as an antioxidant.
Uses & Effectiveness
Insufficient Evidence for
- Side effects of cancer drug treatment. Early research shows that taking agaricus mushroom extract might reduce some of the side effects of chemotherapy, including weakness and loss of appetite.
- A type of inflammatory bowel disease (Crohn disease). Early research shows that taking agaricus mushroom extract does not reduce fatigue or improve symptoms in people with Crohn disease.
- Diabetes. Early research shows that some diabetes medications work better when they are given with agaricus mushroom extract.
- Swelling (inflammation) of the liver caused by hepatitis B virus (hepatitis B). Early research shows that taking agaricus mushroom extract might help reduce liver damage in people with hepatitis B infection.
- Cancer of white blood cells called plasma cells (multiple myeloma). Early research shows that taking agaricus mushroom extract during treatment for multiple myeloma does not improve the response to treatment.
- A type of inflammatory bowel disease (ulcerative colitis). Early research shows that taking agaricus mushroom extract helps reduce fatigue and improve symptoms in people with ulcerative colitis.
- Hardening of the arteries (atherosclerosis).
- Hay fever.
- Heart failure.
- High levels of cholesterol or other fats (lipids) in the blood (hyperlipidemia).
- Weak and brittle bones (osteoporosis).
- Stomach ulcers.
- Other conditions.
Side Effects & SafetyWhen taken by mouth: Agaricus mushroom is POSSIBLY SAFE for most people when taken for up to 12 months. Agaricus mushroom can cause blood sugar to go too low (hypoglycemia) in some people with diabetes. It can also cause nausea, diarrhea and upset stomach.
A few people who took agaricus mushroom during treatment for cancer have developed severe liver damage, and a few have had allergic reactions.
Special Precautions & Warnings:Pregnancy and breast-feeding: There isn't enough reliable information to know if agaricus mushroom is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.
Liver disease: There is some concern that agaricus mushroom might cause liver disease or make it worse. Don't use it if you have liver disease.
Surgery: Agaricus mushroom might lower blood sugar. There is some concern that it might interfere with blood sugar control during surgery. Stop using agaricus mushroom at least 2 weeks before a scheduled surgery.
Be cautious with this combination
Medications used for diabetes (Antidiabetes drugs) interacts with AGARICUS MUSHROOM
Agaricus mushroom might decrease blood sugar in people with type 2 diabetes. Diabetes medications are also used to lower blood sugar. Taking agaricus mushroom along with diabetes medications might cause your blood sugar to go too low. Monitor your blood sugar closely. The dose of your diabetes medication might need to be changed.
Some medications used for diabetes include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), chlorpropamide (Diabinese), glipizide (Glucotrol), tolbutamide (Orinase), and others.
The appropriate dose of agaricus 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 agaricus 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.
