- Thundergod vine (Tripterygium wilfordii) has a long history of use. It has reportedly been used continuously in China for more than 2,000 years. Traditionally, thundergod vine has been used as an anticancer drug, male contraceptive, a drug used to suppress the immune system, and as an anti-inflammatory agent.
- Various clinical trials have indicated the use of thundergod vine as a possible treatment for rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE, a disease of the immune system). There is also evidence suggesting possible benefits of thundergod vine in organ transplantation, asthma, cancer, and kidney, skin, and eye disorders.
