To treat colds or coughs you can make a nice ginger tea by cutting about one inch of ginger root into small pieces and adding to two cups of water and simmering for fifteen minutes. Ginger can also be found in capsules like a lot of other herbs and is a great way to get your dose of ginger for the day. Extracts are also available but are generally used only to treat osteoarthritis.
Teas are a great way to get the benefits of sage all you need to do is steep one teaspoon of sage in a cup of water for about 10 minutes. You can also make a pretty awesome sore throat reliever by combining sage and thyme. Take an ounce of both grind them, and cover them with 16 ounces of apple cider vinegar. Be sure to shake it periodically and let it sit for ten days before using.
