Curcuma longa Linn. (Turmeric): Phytopharmaceutical Approach from Traditional Knowledge to Conventional Medicine

The traditional Indian system of medicine uses turmeric, scientifically known as Curcuma longa Linn. (C. longa). It is a great example of how traditional knowledge about plants has been combined with modern scientific research on medicines. For a long time, turmeric has been used in systems such as Ayurveda, Siddha, and Unani medicine. These systems have shown that turmeric has many health benefits, such as reducing inflammation, fighting free radicals, killing harmful bacteria, and even helping with cancer. The main phytoconstituent (active ingredient) in turmeric is curcumin, along with other compounds such as demethoxycurcumin, bisdemethoxycurcumin, and certain oils such as turmerones. These compounds work by targeting important processes in the body, such as inflammation and cell growth, through pathways like Activated B-Cells, Nuclear Factor kappa B (NF-κB), Mitogen-Activated Protein Kinase (MAPK), and Phosphoinositide 3-kinase (PI3K)/ Protein kinase-B (Akt). New technologies, like eco-friendly ways to extract curcumin, better ways to separate and standardize it, and advanced delivery methods like nanoparticles, have helped make curcumin more stable and easier for the body to use. Clinical studies have shown that turmeric can help with conditions like inflammation, metabolic issues, problems with the brain, and cancer. It is now used not just in traditional remedies but also in health foods, supplements, and conventional drugs. Looking ahead, there are opportunities to create new, better versions of curcumin, use Artificial intelligence (AI) to design medicines, and make herbal mixtures that meet international safety standards.
