Capsaicin. Derived from hot chile peppers, topical capsaicin may be useful for some people in relieving pain. “Capsaicin works by depleting substance P, a compound that conveys the pain sensation from the peripheral to the central nervous system. It takes a couple of days for this to occur,” says David Kiefer, MD, assistant clinical professor of medicine at the Arizona Center for Integrative Medicine.
Ginger. Though more studies are needed, says Dr. Kiefer, ginger extract may help with joint and muscle pain because it contains phytochemicals, which help stop inflammation. Few side effects have been linked to ginger when taken in small doses.Feverfew. Feverfew has been used for centuries to treat headaches, stomachaches, and toothaches. Nowadays it’s also used for migraines and rheumatoid arthritis. More studies are required to confirm whether feverfew is actually effective, but the herb may be worth trying since it hasn’t been associated with serious side effects. Mild side effects include canker sores and irritation of the tongue and lips. Pregnant women should avoid this remedy.
Turmeric. This spice has been used to relieve arthritis pain and heartburn, and to reduce inflammation. It's unclear how turmeric works against pain or inflammation, but its activity may be due to a chemical called curcumin, which has anti-inflammatory properties. Turmeric is usually safe to use, but high doses or long-term use may cause indigestion. Also, people with gallbladder disease should avoid using turmeric.Devil’s Claw. There is some scientific evidence that this South African herb may be effective in managing arthritis and lower back pain, but more research is needed. Side effects are very rare if taken at a therapeutic dose for the short term, but it’s not advised for pregnant women and those with gallstones or stomach or intestinal ulcers.
