I use essential oil from clove bud, oregano and thyme thujanol for their cyst busting properties. mix them in even parts, 1 drop 3 times a day - I drink them with water (it's very strong, don't know if everyone will like it... - I got it from someone specialised in essential oils)
Thyme Thujanol is a very powerfull essential oil - I put the 'normal' thyme (thyme thujanol is expensive, I preserve it for internal use) in the water of my footbaths (haven't tried it together with the epsom salt/hydrogen peroxide).
I use drops of peppermint on a handkerchief when I'm feeling nauseous - it calms it down (not always, but it helps most of the time).
In summertime, I use teatree oil to keep mosquitos and fleas away - it's very efficient! Some people say it's not good, but I'm sure it can't be worse than DEET - I made it through summer with teatree with very few stings.
Teatree is also very efficient for fungals on nails, just rub it on - my husband sometimes has them because of the gym/pool, and it really helps.
Have a look around this site, it has a lot of recipes on it - I haven't got any connection with this side, the specialist I was talking about has nothing to do with it (lives on the other side of the world), just found it on the internet and seemed intresting. http://www.huiles-et-sens.com/Tea-tree-essential-oil/language/en/
this is just about the teatree, but you can look up other oils too.
