From a great deal of reading I've done over the years, it seems like orange essential oil is one of the only things known to stop/prevent tetanus outside of a medical setting. And both it and honey are natural antiseptics.
There's an oil for just about everything! :D
Oils, balms, tinctures, alcohol and poultices were what helped man heal his body for the past 6,000 years. Our modern pharmaceuticals only came about in the last 100-150 years or so. Oh those lovely drugs and all their great damaging side effects. Ok I'm shutting up before I go on a rant.
Keep in mind that I'm someone with a lot of serious medical conditions and I actually do require pharmaceuticals, for various reasons.
Holistic isn't always the answer. But that doesn't mean it can't be the answer most of the time.
