The brain is rich in fats, which makes it particularly vulnerable to lipid peroxidation — a chain reaction in which free radicals damage the fatty membranes of cells. This laboratory study compared the protective activity of five herbs used in traditional medicine, including Kutki (Picrorhiza kurroa) and Haldi (Curcuma longa). Aqueous extracts of each herb were tested against lipid peroxidation triggered by two different pro-oxidants in mouse brain and liver tissue. Free-radical scavenging was also measured with the DPPH assay. All the extracts, including Kutki, inhibited lipid peroxidation in the tissues tested. Among the five herbs, henna, clove and Indian rhubarb showed the strongest inhibitory effects, which the authors linked to their higher reducing and free-radical scavenging capacity.
Key Learnings
- Kutki extract inhibited lipid peroxidation in mouse brain tissue.
- Protection was seen against two different pro-oxidant triggers.
- Haldi (curcumin's source) was also among the herbs tested.
- Henna, clove and Indian rhubarb showed stronger effects than Kutki in this comparison.
- This was tissue-level laboratory testing — it shows antioxidant potential, not effects in people.
