Indian frankincense, also known as boswellia and blessed thistle, is used for many conditions such as coughs, wounds, boils and promoting urine flow, according to WebMD. Boswellia use for these conditions is not based on scientific evidence.
Other common uses for boswellia include diarrhea, infections and promoting milk flow in lactating mothers, states WebMD. Boswellia in large amounts may cause vomiting and stomach irritation in some individuals. Pregnant women are urged not to take boswellia, as there is some evidence that it may be potentially harmful. Although the herb is used to promote milk flow in mothers who are breast-feeding, it is best not to use this product while lactating because there is not enough evidence that it is safe for babies.
