There is a great little book out, called Cholera. I believe if you catch it at the onset with camphora - use the essential oil in alcohol, and it is rubbed on the limbs, homeopathic to the early stages of the disease.Aparently lots of people can be armed with the camphor and save a lot of lives.

Get the book, if possible. It is worth its weight in gold. I have a small supply of camphora essential oil, it is not expensive and well worth having in your pharmacy, also good for helping to antidote any accidental remedy spills.

Warmly,
Maria
