Patchouli Oil What Is Patchouli Oil? Patchouli essential oil comes from a flowering plant in the Lamiaceae family, most commonly referred to as the mint or dead-nettle family. The perennial herb does well in warm to tropical climates and thrives in hot, humid weather, which explains why it can be found in Southeast Asia, including Sri Lanka, Indonesia, the Malay Peninsula, New Guinea, and the Philippines, as well as parts of North East India. https://www.nationalnutrition.ca/aromatherapy-essential-oils/single-essential-oils/patchouli-oil.html #patchouli
