LPT: Homeopathics are bullshit, except for ones used as ingredients in actual products or medication.

For example:

Tea Tree Oil - Paul Mitchell, Body Shop, Head & Shoulders - "Moisturizes your hair and scalp!" - It burns off dandruff (and beardruff). Also good for acne. (Use sparingly)

Eucalyptus Oil - Vicks Vapo Rub, Sephora, Bath and Body works - "Cleanses the pores and spirit!" - It opens your sinuses (so you can breathe). But another good one for acne too.

Clove Oil - Colgate, various minor companies - "Jesus, this shit stinks" - It stops tooth pain. In seconds. It's a damn miracle. Oragel is shit in comparison. The active chemical in Clove Oil is Eugenol, an anti-inflammatory numbing agent. But unfortunately, it's about all it's good for. (Aside from the weirdos who cook with it) And it's very, very, pungent.

Just keep in mind that while yes, you are being smart by not buying the super branded diluted garbage stuff, there's only a couple of drops of this stuff in any of the actual products you buy. So don't go crazy and wash your face in eucalyptus. That will burn the hell out of your skin.
