Centella asiatica (cica) in skincare: what Cleveland Clinic says

Reviewed October 17, 2026

The short answer

Centella asiatica goes by several names on labels, including cica, tiger grass and gotu kola. Cleveland Clinic says the science on it is still fairly preliminary, that few studies exist, and that most people tolerate it. It also lists groups who should ask a clinician before using it, and it advises a patch test.

What is it?

It is a plant with an old track record in Ayurveda and Chinese traditional medicine. Cleveland Clinic names four active compounds that skin-care makers use: madecassoside, asiaticoside, madecassic acid and asiatic acid.

What the source says it may do

• A dermatology physician assistant quoted by Cleveland Clinic says it helps skin hold moisture and may calm redness, which matters for dry or sensitive skin such as eczema or rosacea.
• The same expert says it may help burns and wounds when paired with products such as petrolatum jelly.
• On aging, Cleveland Clinic says there is some evidence it may reduce photoaging and the look of scars and cellulite, but more research is needed before anything definitive can be said.

Cautions from the source

• Allergy is rare but possible. Typical reactions are a burning feeling or contact dermatitis.
• Cleveland Clinic advises testing on the inner arm and waiting at least 24 hours before putting a product on the face.
• Ask a dermatology provider first if you are under 18, pregnant or breastfeeding, or have had liver trouble such as hepatitis, or skin cancer, in the past.
• Cleveland Clinic says large amounts, as from eating it or by injection, can cause headaches, stomach upset, drowsiness, dizziness and miscarriage. It says skin-care products alone are unlikely to reach that level.

How to read it on a label

US cosmetic labels generally list ingredients in descending order of amount, but anything at 1% or less can appear in any order after those above 1%. Its position does not tell you the exact concentration. Judge the whole product, how it feels on your skin, and what changes when you add or drop it.

What not to conclude

This page does not say centella asiatica will fix eczema, scars or wrinkles, or that every product containing it is gentle. The evidence Cleveland Clinic describes is limited, and its benefit claims come from one expert's account. If a product stings or leaves a rash, stop using it and ask a dermatologist.
