Turmeric, a plant native mainly to southern Asia and growing up to three feet tall, has long been used in traditional Chinese medicine to relieve muscle pain, cramps and digestive problems. However, it is only recently that attention has begun to be paid to its health-promoting properties. Curcumin, the pigment that gives turmeric its bright yellow color, is considered the active agent responsible for its benefits, thanks to its antioxidant and anti-inflammatory properties.

Here are some of the beneficial effects attributed to turmeric:

Anti-inflammatory: Turmeric is known for its effectiveness against inflammation and muscle pain associated with conditions such as rheumatism, osteoarthritis and arthritis. Studies have shown that the curcumin found in turmeric can inhibit inflammatory processes in the body.

Cancer prevention: The curcumin present in turmeric has antioxidant properties which can help prevent the onset of certain cancers and slow their progression. Preliminary studies also suggest that curcumin may potentiate the effectiveness of cancer treatments.

Improved digestion: Turmeric is known for its digestive properties and can help treat certain digestive disorders such as stomach ulcers, nausea and irritable bowel syndrome. It can also reduce excessive stomach acid.

Antioxidant effect: The curcumin found in turmeric has antioxidant properties, meaning it can protect organs and cells from damage caused by free radicals, unstable molecules that can damage cells and contribute to premature aging and to certain diseases.

Positive cardiovascular effects: Studies in animal models suggest that turmeric may help slow the oxidation of LDL cholesterol (“bad cholesterol”) and reduce total cholesterol levels, which may have a beneficial effect on cardiovascular health.

It is important to note that the bioavailability of curcumin, i.e. its ability to be absorbed and used by the body, is relatively low. However, some research has explored strategies to improve the bioavailability of curcumin, such as combining it with piperine, a compound found in black pepper, which may increase its absorption.

Several scientific studies have been carried out to evaluate the effects of turmeric on health. Some preliminary studies suggest promising effects, but additional research is needed to confirm these benefits and determine optimal doses.
