In Tibet, incense is used as medicine. One of the most famous medicines, also available as incense, is agar. Agar is also known as agarwood, aloeswood, eaglewood; the distillate is oud — the prized ingredient in Arabic perfumes. There are different formulas, and as you can see, the one I have is Agar 31 (I believe the number relates to the amount of ingredients). Agar is good for ailments relating to the Wind element (rLung in Tibetan medicine, vata in ayurvedic medicine, movement of Qi in Chinese medicine). Wind ailments usually involve mental issues, such as stress, anxiety, insomnia, and headaches. Bob Flaws recommends agar incense in his books Curing insomnia naturally with Chinese medicine and Curing headaches naturally with Chinese medicine: “as the smoke rises, breathe in deeply. This can be done on a regular basis one or more times per day during the premenstruum or on an as-needed basis by those suffering from restlessnesss, nervousness, anxiety, irritability, and depression.”  The name for agar in Chinese is Chen Xiang. It means sinking fragrance, as the wood can bring down the excess energy which is disturbing the mind.
