The Definition of Ganoderma

Ganoderma is a tree fungus that has been used medicinally for centuries, dating back to ancient China. The name ganoderma refers to its scientific name--Ganoderma lucidum--but it is commonly called Reishi mushroom. Studies have demonstrated that the mushroom has some medicinal properties, but how it works in the body is not fully understood, according to New York University Langone Medical Center. Additionally, more research is necessary to demonstrate its effectiveness in treating specific conditions. Always consult with a knowledgeable health professional before using ganoderma supplements to improve your health.

Physical Description

Ganoderma lucidum is a polypore fungus that produces tubes underneath the fruiting body, which is where the spores originate. It is brownish-red in color and typically can be found growing on deciduous, hard-wood trees, commonly maple and oak trees, according to Cornell University. Both the cap and the stem of the mushroom are used in medicinal applications. Consult your medical practitioner before using ganoderma supplements.

Medicinal Uses

Today, ganoderma has many purported medicinal uses. It has been used to treat viral infections, autoimmune disorders, fatigue, HIV and AIDS, inflammation and high cholesterol, and also to boost the immune system and for strength and stamina, according to the Memorial Sloan-Kettering Cancer Center. It is also sometimes promoted as a cure-all or a tool for preventing cancer. However, the effects of ganoderma in the body have not been proved with reliable and double-blind human studies using a placebo as a control, the Langone Medical Center reports. Before using it to improve your health, speak with a qualified medical practitioner about potential risks and benefits.

Dosage

The recommended adult dose for ganoderma is 2g to 6g daily, according to Langone Medical Center. It can be taken either in raw form or a concentrated extract. No matter the form taken, it is best taken after meals. Reishi is also used in traditional Chinese medicine, but in these applications it is typically taken along with other fungi.

Safety Warnings

Ganoderma is consumed as a food in parts of Asia. Because of this, it is generally considered safe as a supplement. However, studies have demonstrated that it may impair blood clotting, according to Langone Medical Center. Because of this risk, it should not be used by people with bleeding disorders or those taking blood-thinning medications. Additionally, people about to undergo surgery and women scheduled to give birth should avoid the supplement in the periods before and after the event. Also, the safety of ganoderma has not been studied in children, people with liver and kidney conditions and women who are pregnant or breastfeeding. Always speak with a knowledgeable health professional to make sure you understand potential risks before using ganoderma.

Side Effects

Many people can take reishi mushroom supplements without experiencing side effects. However, ganoderma has some known side effects users should be aware of. Known side effects include upset stomach, diarrhea, constipation, dry mouth, dizziness, nosebleeds, bone pain and skin irritation, according to Drugs.com. Always consult with a medical professional before using ganoderma supplements to treat a medical condition.
