In recent years, kava has been researched for its potential pain-relieving properties as well as it’s calming and anxiety reducing properties.

The active compounds in kava, called kavalactones, are believed to act on the brain to produce a calming effect. Studies have found that kavalactones may increase the levels of certain neurotransmitters, such as GABA, which can help to reduce pain and promote relaxation.

One study, published in the Journal of Clinical Pharmacy and Therapeutics in 2002, found that kava was effective in reducing pain in people with chronic tension headaches. The study involved 60 participants with chronic tension headaches, who were randomized to receive either kava or a placebo for four weeks. The researchers found that those who received kava had significant reductions in pain compared to those who received the placebo.

Another study, published in the Journal of Clinical Psychopharmacology in 2005, found that kava may be effective in reducing pain in people with fibromyalgia. The study involved 45 participants with fibromyalgia, who were randomized to receive either kava or a placebo for eight weeks. The researchers found that those who received kava had significant reductions in pain compared to those who received the placebo.

Kava has also been found to be effective in reducing pain associated with menstrual cramps, and several studies have shown that kava can be effective in reducing pain associated with neuropathic pain conditions like complex regional pain syndrome and diabetic neuropathy.

It is important to note that more research is needed to fully understand the pain-relieving effects of kava and its safety profile. Kava should not be used as a substitute for conventional treatments for pain without consulting a healthcare professional.
