Risks & Warnings
Botanical extracts can cause irritation or sensitization in some users; CIR notes reported skin problems in a small clinical use study and case reports of dermatitis with Equisetum arvense exposure. Oral toxicity reports are not directly comparable to cosmetic topical use, but they support a cautious approach in highly reactive skin.
