Conjuntivitus: put a cold teabag on the eye and lie back for a while, (don’t re-use, instead dry for fire lighters). This remedy cured my young son in three days, his cousin was treated with prescription medicine and took three weeks, cousins mother is a doctor and poo pooed the teabags. Works on pets too, you just have to hold it on them.
Athletes foot? You might think this is gross but urine can cure it in no time, the shower is a good start for the squeamish, store in a bottle and add a few drops if walking around outside for the more adventurous.
Indigestion: put 1 teaspoon of Sodium bicarb (baking soda) in a glass of water stir till clear and down the hatch, tastes yuk but works better than most other remedies and it’s cheap!
If out or you have kids that won’t go for this idea try ginger beer, Bunderburg works not too bad.
