Are Reishi Mushrooms (Lingzhi) good for high blood pressure?

There isn't really a definitive answer as to whether Reishi Mushroom does lower blood pressure or not. Lingzhi doesn't seem to affect blood pressure in normal individuals or people with slightly higher blood pressure, though it does seem to help in individuals with severely high blood pressure.

Aside from this, there are several other potential benefits of Reishi mushrooms.

It is not confirmed yet if Reishi Mushrooms can treat blood pressure. However, some persons with high blood pressure reported that their blood pressure got lowered after using Reishi mushrooms. I would not consider Reishi as a cure yet, you should see your doctor for proper medical advice.
