Hops pillows should be refilled every few months to retain their activity. It is also wise to only use them for 6 to 7 weeks and then take a break for a couple of weeks. The dogs will eat them and there is no antidote. Hops should be used sparingly during pregnancy due to their estrogenic effects. Because of their cold and drying nature, they should not be used in people whose symptomology or constitution would be aggravated by them.
Hops are an effective aid in combating nervousness, tension, digestive disorders and insomnia.
Although much less potent than pharmaceutical sleep aids, they still have a powerful effect and need to be used appropriately for optimal performance. A qualified or experienced herbalist can help. Grieve, M., A Modern Herbal , Dover Publications, Inc., New York, Vol.
