Patchouli is a very fragrant herb with soft oval leaves and square stems. It grows up to 1m in height and provides an unusual odour that is nonetheless characteristic of patchouli when the leaves are rubbed.

Common uses: Patchouli is recognised by aromatherapists as being effective for combating nervous disorders, helping with dandruff, sores, acne, skin irritations and acne.
The specific properties include use as an antidepressant, anti-inflammatory, antimicrobal, antiseptic, astringent, bactericidal, deodorant, fungicidal, 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.

Blends well with: sandalwood, bergamot, cedarwood, rose, sweet orange, cassia, myrrh, opopanax, and clary sage.

Aromatic scent: Patchouli has a warm, earthy aroma with fresh fruit-like tones.

History: It is one of the few essential oils with the distinction of improving with age.  Possibly originated in Malaysia although the word apparently comes from the south Indian Tamil language, patch, meaning 'green', and ilaimeaning 'leaf'.  As well as for perfume and medicine, patchouli is used for scenting carpets, shawls and woven materials, and for perfuming ink.
