The thing about a lot of hokey medicines is that traditions have remained traditions for a reason. Sure, some of it is insanity but a lot of it is very good. Chinese people had been sticking needles into each other for a while before acupuncture was recognized as helpful by modern medicine.

Even what doesn't work is a decent enough placebos.

I've studied clinical aromatherapy for several years and although some people (and a lot of companies) are in it for the money, it can work very well for many illnesses. It does work better in conjunction with modern medicine, but nothing reaches the brain faster than smell.

Also, more isn't always better. Like the study explained, the whiff of rosemary was enough. One drop is enough. 10-20 drops in a capsule taken three times a day via the orifice of your choice is going way overboard.

The downside to aromatherapy is that it's very expensive, especially if the oils are high quality and unadulterated. I still have yet to convince myself to drop almost $200 for a 5ml bottle of Rose essential oil.

I laughed because I just finished googling where to buy rosemary oil. It's cheap enough that I would give it a try.
