Turmeric (Curcuma longa)


Turmeric Overview:

Turmeric has been used as both a food and medicine for thousands of years. It's orange pigment is due to the curcumin content, which is also one of the main active phytochemicals in the plant.

Turmeric is a staple in Indian, and other Southeast Asian cooking, and is thought to provide adaptogenic, and general health-promiting effects in these regions.

There has been a lot of study on turmeric in recent decades investigating its effects on cancer, cardiovascular disease, diabetes, inflammatory conditions, and as an antibacterial and antiviral. Turmeric has shown promise in all of these areas.

The major problem with turmeric is its low bioavailability. Cooking the root for long periods of time such as with curry, or soups, can improve this bioavailability in the gut, but is still far less than 50% bioavailable. This is an issue when trying to use turmeric for systemic conditions, and requires a large amount of the herb to have any effect whatsoever. Combining turmeric with other herbs like black pepper (the piperine content) has shown dramatic improvements in bioavailability.
