It is likely safe for most adults to use gotu kola on the skin and to take it orally in small doses for a short time. It may be safe for women who are pregnant to use it on the skin, but they should not take it orally. Not enough studies have been done to say whether it is safe to use for a long period. It is also not known whether it is safe to take by women who are breastfeeding.
