While trekking in the Himalayas we learn some tips from the locals. Instead of carrying modern medicines, I find the following traditional method very useful… 

Ginger tea or hot ginger water

To keep you warm in cold weather.

Garlic soup

To prevent high altitute sickness. Add lots of garlic in the soup you normally eat when you reach the height of 2000m above sea level.

Pop corn or banana

To prevent cramp.

Newspaper in shoes overnight

Stuck newspaper (or news print) in your wet tracking shoes overnight should help to dry it faster as newspaper absorbs the moise in your tracking shoes.
