The function of patchouli
Patchouli oil is often referred to as patchouli, and due to its rich woody aroma, it has been used in perfumes and fragrances for centuries. This oil is extracted from the leaf distillation of patchouli, a plant widely distributed in Asia and the Caribbean. Traditionally, patchouli has been used to relax, treat headaches, colds, nausea, diarrhea and abdominal pain; it is also considered an insect repellent, which is used in Japan and Malaysia to treat venomous snake bites (Wikipedia).
According to dermaxime.com, patchouli has the properties of a cavitator (a healing product that aids scar tissue formation) and cellular defense (stimulates cell regeneration), stimulating new cell regeneration and calming inflamed skin. Because of its anti-inflammatory properties and the prevention of scarring, it is an ingredient in acne treatment formulas. Patchouli also has astringent properties that revitalize the skin, diuretic properties that reduce excess moisture and puffiness in the body, and it also has antiseptic properties.
Safety and side effects
Cosmetic databases consider patchouli to be a low-risk ingredient with a 95% safety profile, despite its potential irritation to certain sensitive skin.
