Frequently asked questiosn (FAQs)

What are other common names for Reishi?

The scientific name for Red Reishi is Ganoderma lucidum, which Chinese medicine commonly refers to as Ling Zhi.

What is "Japanese Reishi"?

The term "Japanese Reishi" does not refer to an actual species of Ganoderma ( Ganodermataceae), a family of Polypore ( Polyporaceae ), but instead to Reishi that is grown, cultivated, and/or manufactured in Japan, the country recognized worldwide for maintaining the highest product quality and business standards in the Reishi industry.

Why is it important to buy authentic Japanese Reishi products?

Purchasing counterfeit Japanese Reishi products exposes you to significant health risks in addition to financial losses. Retailers that buy and resell counterfeit products may also be prosecuted according to the governing laws in their jurisdiction. Although consumers obviously lose money when purchasing counterfeit products that do not provide the health benefits claimed, the greater danger lies in the potentially serious side effects people may suffer since Reishi products from a fraudulent manufacturer or packager are more likely to be of poorer quality and may possibly contain harmful ingredients or bacteria.

How can I find out if I have purchased a counterfeit Japanese Reishi product?

The easiest way to find out if you have purchased a counterfeit product is to contact the Japan Reishi Association for the current list of approved Japanese Reishi products, or to send the packaging of the product in question to our mailing address. Our associates will carefully investigate the product and reseller, and we will contact you to let you know what actions may be taken if you have been sold a counterfeit product.
