Agaricus (Agaricus blazei) is a type of medicinal mushroom. In folk medicine, agaricus is used to treat a variety of health conditions, including major diseases like cancer and diabetes. Although research on the health effects of agaricus is fairly limited, some preliminary studies show that agaricus may offer certain health benefits.
Uses for Agaricus
Agaricus is often touted as a natural remedy for the following health problems:
Benefits of Agaricus
So far, relatively few scientific studies have tested the potential health benefits of consuming agaricus. However, preliminary research suggests that agaricus may have some beneficial effects. Here's a look at some key study findings:
Agaricus may aid in diabetes control, according to a 2007 study in the Journal of Alternative and Complementary Medicine. For the study, 72 patients with type 2 diabetes were given either agaricus extract or a placebo every day for 12 weeks. By the end of the study, members of the agaricus group showed significantly greater improvements in insulin resistance compared to those given the placebo.
In an earlier study (published in Biotechnology Letters in 2005), scientists discovered that beta-glucan found in agaricus helped reduce blood sugar levels and lower cholesterol in diabetic rats.
2) Immune System
Certain compounds in agaricus may help stimulate the immune system and reduce inflammation, according to a 2011 research review in the Journal of Medicinal Food. However, the review's authors noted that clinical trials are needed to test the immune-enhancing and anti-inflammatory effects of agaricus in humans.
Several studies indicate that agaricus may help fight some forms of cancer. For instance, in a 2009 study from the Journal of Nutritional Biochemistry, tests on cancer cells and on mice revealed that agaricus extract may inhibit the growth of prostate cancer. In addition, a 2011 study in Biochimica et Biophysica Acta found that agaricus may possess anti-tumor properties that could aid in the treatment of leukemia.
Little is known about the safety of taking agaricus in the long term. However, there's some concern that agaricus may harm liver health. For instance, in a 2006 report from the Japanese Journal of Clinical Oncology, scientists linked consumption of agaricus to severe liver damage in cancer patients. It's thought that taking agaricus may increase your levels of certain liver enzymes.
Additionally, a 2011 report in Microbiological Research found that agaricus may have estrogen-like activity. Therefore, medical experts warn that people with hormone-sensitive cancer (including some types of breast cancer and ovarian cancer) take caution when consuming agaricus.
Since agaricus may also decrease your blood sugar levels, patients using medications to lower their blood sugar should consult a physician prior to consuming agaricus.
Where to Find Agaricus
Widely available online, supplements containing agaricus are also sold in many natural-food stores and in stores specializing in dietary supplements.
Using Agaricus for Health
Due to a lack of supporting research, it's too soon to recommend agaricus as a standard treatment for any health condition. If you're considering agaricus for a chronic condition, make sure to consult your physician before starting. Self-treating a chronic condition with agaricus and avoiding or delaying standard care may have serious consequences.
