Fresh ginger is natures antiseptic. Use it for sore throats in tea.
If you have a cough chew a finger nail size peice raw. Keep chewing to release the juice. Do that once a day for 3-4 days. Cough gone
I have several methods:
1) Gargle cider vinegar and follow with honey (to mask the taste as much as anything)
2) Eat a spicy curry or food containing Turmeric (my cold cure is a teaspoon of turmeric in a tablespoon of milk, heated on the hob in a spoon)
3) Gargling TCP
4) Cutting out milk as this decreases the production of mucus and stops irritation.
I swallow a teaspoon full of Aloe Vera Gelly. Vile tasting but it does the trick for me. Aloe is well known for its healing properties and I have been using the stuff daily to keep my horrible eczema at bay since the mid 90s.
The brand I use is pretty much pure Aloe, with no additional rubbish in it so I feel quite happy to ingest the stuff. Normally I reserve the Gelly for cuts, grazes, being bitten by dogs, burns etc (very handy in my line of work)
