Turmeric is a flowering rhizome.
The name appears to derive from Middle English/early modern English as turmeryte or tarmaret having uncertain origin. There may be Latin origin, terra merita (merited earth).
The active compound curcumin is believed to have a wide range of biological effects including anti-inflammatory, antioxidant, antitumour, antibacterial, and antiviral activities, which indicate potential in clinical medicine.
According to the National Center for Complementary and Alternative Medicine, “there is little reliable evidence to support the use of turmeric for any health condition because few clinical trials have been conducted.”
Turmeric is considered auspicious and holy in India and has been used in various Hindu ceremonies for millennia. It remains popular in India for wedding and religious ceremonies.
