It includes a couple of traditional herbal alternatives, some familiar to you, others probably not.
The first one would be essential peppermint oil. This is best applied in the way of a good massage. Even if you have little time and money, your painful back should warrant this investment once a week - this way return to real back care. Essential peppermint
oil improves blood circulation, relaxes muscles and reduces inflammations. In combination with massage it is very relieving for back pain.

Kratom also is widely available over the Internet and this is also the source for a wide variety of recipes for various Kratom preparations to help against back pain.
