Since the popularity of brewing, we have lost touch with the many uses of hops. Hop tea has dated back to the ancient times. The hop oils can help people in many ways. Like the sleep pillows, hop tea aids in insomnia, can promote appetite, cleanses your blood, can relieve arthritis pain, relieve gas and cramps by soothing muscle spasms and some say it can aid smokers with their cravings and nerves (I am not sure about this. I always want to smoke more when I drink). I've also read, it can help women develop more milk while breast feeding and possibly cancer.
Here is a basic recipe I found online.
Basic Hop Infusion or Tea
Place 1 ounce dried hops per 1 quart jar
Fill with boiling water
Strong Infusion ~ Cover jar. Steep for atleast 4 hours but not more than overnight. Strain infusion and store in refrigerator for up to 48 hours. Serve hot or cold.
Hop Tea ~ Steep for 10-20 minutes. Strain and drink. This method is milder flavored as well as less effective. Serve hot or cold
Note: Many people will add other herbs such as, chamomile, peppermint, lemon grass, ginger or other herbs, which can aide in many ways as well.
Chamomile - Has antibacterial, antiseptic and disinfectant properties. Probably why most people drink it when they are sick.
Peppermint - Aides in digestive, respiratory and circulatory systems and is also an anti-inflammatory and antiseptic herb
Lemon Grass - Improves circulation, digestion and promotes oxygen intake
Ginger - Aides respiratory and digestive systems
Haven't got a chance to look too much into it, but OSU hop program has developed a hop that would be great for making tea. This variety does not have as much bittering properties as other varieties. It's called the "Teamaker". Here is an article I found about the variety. Click Here.
If you know more about the "Teamaker," please send me an email. Thanks!
