Turmeric is a traditional spice extracted from the rhizomes of *Curcuma longa*, a ginger family member (Zingiberaceae). Turmeric, also known as the "Golden Spice of India," has been utilized for pharmacological purposes in India for ages. It has been used as a household remedy for biliary disorders, anorexia, cough, diabetic sores, hepatic disorders, rheumatism, and sinusitis in traditional medicine. Turmeric and its compounds, namely curcumin and essential oils, have a wide range of biological effects in addition to their usage as a spice and pigment. Curcumin, Turmeric's active ingredient, is being studied by scientists for its antioxidant activity, anti-inflammatory properties, antimetabolic syndrome activities, neuroprotective activity, antimicrobial effects, antiarthritis effects, anti-asthma, anti-obesity, cardio and liver toxicity protection activity, anti-depression and anxiety activities, anti-carcinogenic, anti-mutagenic, anticoagulant, anti-fertility activity, anti-diabetic, anti-fibrotic, anti-venom, anti-ulcer, hypotensive and hypocholesterolemic activities. As a result, turmeric and its compounds have the potential to be used in modern medicine to cure a wide range of diseases.
