The use of Reishi as an herbal remedy dates back longer than any other medicinal mushroom in historic literature. The first written record can be found in Shen Nong's Herbal Classic, dating back two thousand years. Reishi (a.k.a. Ganoderma or Ling Zhi) is often considered a panacea " cure-all " in Traditional Chinese Medicine. While it may not be literally accurate to refer to Reishi as a cure-all, the fact that it appears to act as an inflammation modulator may be one of many reasons for its age-old veneration in the Orient.
While researching scientific papers in preparation for this article, seventeen out of nineteen presented positive results in using Reishi extract to treat inflammatory conditions. This appears to validate the traditional use of the herb in China, where it has long been used as an analgesic, and prescribed to treat inflammation and arthritis. Only two studies out of the nineteen that are referenced for this article showed inconclusive results. Both of those studies were conducted at the same institution. (1,2)
Regarding anti-inflammatory properties in general, a study out of India (2003) demonstrated that Reishi decreased inflammation in cases of acute or chronic edema by 56% and 60% respectively. (3) An earlier American study (1993) had already shown that, water extracts of G. pentaphyllum and G. lucidum [Reishi] were found to possess significant anti-inflammatory activity. (4) In the references are seven additional papers listed which all conclude that Reishi (Ganoderma lucidum) possesses potent anti-inflammatory qualities. (5,6,7,8,9,10,11)
Other research has been conducted on Reishi extract that relate specifically to arthritis. In 2006, Kenneth Blum et al. published findings in support of both the effectiveness and safety of using Reishi extract for "joint health," providing "clinical evidence" to back up their claim. (12)
The same year, another study summarized findings that Reishi in combination with a Chinese herbal remedy known as San-Miao-San demonstrated a positive "immunomodulatory effect" on rheumatoid arthritis. (13)
The answer as to how, precisely, Reishi extract accomplishes this "immunomodulatory effect" may have been given by another Chinese study the following year, which states that an isolated Reishi polysaccharide peptide "significantly inhibited" RASF, which is an indicator of rheumatoid arthritis. (RASF stands for "Rheumatoid Arthritis Synovial Fibroblasts.") (14)
Several additional papers have been published that summarize positive results in the use of Reishi against arthritis. (15,16,17) One even states that Reishi compares favorably to prednisone, albeit without side effects. (18) On the other hand, a separate study found that supplementing with Reishi helped balance the side effects of prednisolone* that were experienced by some patients, including protein in the urine and cell toxicity. (19) (Prednisolone is the active compound of prednisone, which gets broken down by the liver and converted to prednisolone.)
In conclusion, the body of research does seem to support the use of Reishi extract in cases of arthritis. Remember that it is important to always work with a licensed medical practitioner when using any herb for medicinal purposes.
Note: "Reishi" is the Japanese name on the mushroom known in English as "Varnished Conk." It actually encompasses several closely related species, the most common of which is Ganoderma lucidum (Common Reishi or Red Reishi). This species can be found in the U.S. but is much more common in South East Asia. It is also well known by its Chinese name, Ling Zhi.
Other species frequently referred to as Reishi include: Ganoderma tsugae (Hemlock Reishi, common on Hemlocks in Eastern U.S.), Ganoderma sinense ("Black Reishi), Ganoderma resinaceum (Red Reishi), Ganoderma japonicum (Purple Reishi) and Ganoderma neo-japonicum (no common name or simply Reishi). - 14130
