Echinacea can be taken as a tincture, tablet, or capsule to help speed up the recovery time of colds, chest infections, and sore throats. For sore throats gargle a diluted tincture of echinacea to help ease the symptoms. Like I mentioned earlier echinacea can be used to treat tooth aches, all you need to do is chew on the root. I can remember doing this in high school when we practiced range judging, and it is a very effective way of treating a tooth ache. A more desirable method however might be to turn the root into a tea rather than chewing on it.
Ground cinnamon is very safe, the volatile oils can however cause a skin rash. Small amounts of coumarin can be found in Cassia and other cinnamons, generally only large doses of this compound will cause blood-thinning and liver problems, but it's something to be aware of. Also if you're planning on having surgery you should stop the use of cinnamon at least one week before going in as it has a blood thinning effect. You should also take care to monitor your blood sugar to avoid an unsafe drop in blood pressure.
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.
