Science
Mechanism of Action
This root powder exerts its effects through several mechanisms on the skin. It possesses anti-inflammatory properties, attributed to compounds like terpenes and sesquiterpene lactones (e.g., costunolide), which help mitigate irritation, redness, and itchiness. Significant antioxidant activity is observed due to the presence of chlorogenic acid, phenols, and flavonoids, contributing to protection against oxidative stress. Furthermore, it demonstrates broad antimicrobial action, inhibiting the growth of various Gram-positive and Gram-negative bacteria, as well as fungi, which may aid in addressing concerns such as acne and body odor.

- Individuals with known allergies to plants within the Asteraceae/Compositae family (e.g., ragweed, chrysanthemums, marigolds, daisies) should avoid use due to potential allergic reactions.
Safety
Safety Profile
A critical safety concern for Saussurea lappa (Costus) products is the potential presence of aristolochic acid, a known nephrotoxin and carcinogen. Any product containing this ingredient must be rigorously laboratory tested to confirm the absence of aristolochic acid, as contaminated products are deemed unsafe. Currently, there is insufficient reliable information regarding the safety or potential side effects specifically when Saussurea lappa is applied topically to the skin. Additionally, a moderate risk of allergic reaction exists for individuals with sensitivities to the Asteraceae/Compositae plant family.
