Can turmeric alleviate joint pain?

The turmeric is a perennial herbaceous plant belonging to the Zingiberaceae family that grows on the Asian and African continents. This plant has rhizomes, from which it is possible to extract a powder of yellow-orange color with a thousand virtues for the skin. This ingredient has been used for several centuries by traditional Chinese and Indian medicines for its antioxidant and anti-inflammatory properties. Turmeric powder is particularly recognized for its ability to alleviate mild forms of acne, eczema , or psoriasis.

The anti-inflammatory properties of turmeric make it a good candidate for relieving joint pain. Indeed, it contains curcumin, a molecule that acts on many biological processes, including the induction of the COX-2 protein. By inhibiting the activity of this membrane protein, curcumin prevents the release of prostaglandins, which play a pathological role and contribute to the sensation of pain. This molecule also inhibits the synthesis of certain pro-inflammatory cytokines, such as interleukins 1α and 6 (IL-1α and IL-6) and tumor necrosis factor (TNF-α). According to some studies, these cytokines contribute to the progression of cartilage loss, a characteristic of arthritis.

Scientists have recently taken an interest in the effect of turmeric on joint pain and conducted a study on 70 participants suffering from knee arthritis. Among these individuals, half received two capsules daily containing 500 mg of turmeric, while the other half received two placebo tablets for 12 weeks. At the end of the experiment, the researchers noted a better effectiveness of the capsules with turmeric than the placebo capsules in relieving joint pain. However, they did not observe any changes in the composition of the cartilage over these 12 weeks.

The turmeric can also be incorporated into a cream and used in a topical application to alleviate joint pain. It is generally recommended to accompany it with a massage, in order to relax the joint. However, to date, there is no scientific evidence of the effectiveness of this ingredient incorporated into a cream to alleviate joint pain.
