Mint/Menthol:

Present in Formula #1. Peppermint and Spearmint blend nicely with the other EO's in Herbal Spray. The entire peppermint plant contains menthol, an organic compound with local anesthetic properties which provides a wonderful cooling sensation while it naturally alleviates discomfort. While safe for all ages, this cooling sensation may be interpreted by small children as a 'burning sensation' and cause them discomfort.  It also has antibacterial, antiviral, anti-inflammatory, insecticidal, antispasmodic and carminative properties.

There are some risks in using too much peppermint oil, including allergic reaction, heartburn, and headaches. Basically, the same rules apply to using peppermint oil as all EO's: patch test before use, do not use if pregnant or breast feeding.

The spearmint does not contain menthol, and is used for it's scent and other beneficial properties.
