(posted by Kiri Sue on the 4herbs list from Prevention's Natural Healing Guide 2000 page 223)

Greetings. I was just thinking that with all the posting of herbs for medical treatment not only on this list but on others over the last month, now would be the time to caution folks. Herbs are not purely safe. There are precautions with them just like with medicines. There can be side effects or even death. Prevention magazine puts out a great book called Natural Healing
Guide 2000
. In the back is a safe use guide that I thought I would type up and send out thru the list. The next paragraph is paraphrased from Prevention's Natural Healing Guide 2000 page 223.

When using herbs, use common sense above all. Don't mix and match nilly willy, but do research and make sure the herbs you are taking are compatible. If you are under a doctor's care, pregnant, nursing or taking medication, do not use herbs or essential oils without consulting your doctor whether that is a allopathic, naturopath or homeopathic physician.

Essential oils should never be taken internally because they are so concentrated they can be toxic. Essential oils usually should be diluted in a carrier oil or cream. It is wise to do a patch test and wait for an hour to see if irritation occurs. And remember with herbs, do not exceed the recommended dose, more is not better. If you are going to use herbs, be aware of the precautions and possible side effects so that you may enjoy them safely.

The following is directly from Prevention's Natural Healing Guide 2000. I will send several parts. As with all things, do your own research as well.

Bright Blessings, Kiri Sue
