Turmeric (Curcuma longa)
What turmeric is, how classical Indian texts describe it, what published studies show and where they fall short, how to use it safely, and which GraceYes products contain it.
Names
Haldi (Hindi); Haridra (Sanskrit). The part used is the cured rhizome.
Classical Indian view
API Vol I lists it as Varnya, Kusthaghna (for skin disorders) and Vishaghna, with uses in Tvagroga (skin disease) and Vrana (wounds). Charaka Samhita (Sutrasthana 4.11) places Haridra in the Kushthaghna and Vishaghna groups.
Key compounds
Curcuminoids (mainly curcumin) and ar-turmerone.
What studies show
- A systematic review found 18 human studies of turmeric on skin. Ten showed significant improvement, but the authors call the evidence "early" (PubMed).
- A 2023 review covers topical-only clinical use (PubMed).
- In the lab, turmeric reduced inflammatory signals triggered by acne bacteria (PubMed).
Safety
Allergic contact dermatitis is documented (PubMed), so patch test. It stains skin and fabric yellow.
