Patchouli oil is recognized by aromatherapists as being effective for combating nervous disorders, helping with dandruff, sores, skin irritations and acne. The specific properties include use as an antidepressant, anti-inflammatory, anti-emetic, anti-microbial, anti-phlogistic, antiseptic, antitoxic, antiviral, aphrodisiac, astringent, bactericidal, carminative, deodorant, digestive, diuretic, febrifuge, fungicidal, nerving, prophylactic, stimulating and tonic agent. In the perfumery industry, it is interesting to note that Patchouli improves with age, and that the aged product is what is preferred over freshly harvested. In aromatherapy, Patchouli is an excellent fixative that can help extend other, more expensive oils.
