Peppermint is a hybrid mint, a cross between watermint and spearmint.

Because peppermint oil has analgesic, anti-inflammatory and anti-spasmodic properties, it not only can relieve pain and inflammation but can also calm the spasms that cause muscle cramps. Due to its refreshing nature, peppermint is able to provide relief from stress, depression and mental exhaustion. It is also effective against feeling anxious and restless.
