The Neem Leaf Extract has long been used for a variety of health-related purposes. While neem oil is generally applied to the scalp or skin to treat conditions like dandruff and acne, the extract of the neem leaf is typically taken orally. Neem is used for tooth plaque, gum disease (gingivitis), lice, to repel insects, and for other conditions, but there is no good scientific evidence to support most of these uses. The offered Neem extract is very safe for use.
