I just got around to catching up on my mail here...I thought you guys were discussing *growing* echinacea! Gleaned from a variety of sources: Echniacea: One of the 'blood purifying' herbs that can help to stimulate an immune system that has become sluggish because of poor diet, illness or stress. Should not be used by pregnant women or by persons who have allergies to plants in the Sunflower family Goldenseal: An antibiotic and antibactierial herb that is effective in cleaning and clearing mucous membrane tissues, has a number of uses including reducing blood pressure, assisting in the healing of ulcers and digestive system disorders. Should not be used by pregnant women or persons with ragweed allergies. For best cold and flu prevention, echinacea and goldenseal should be alternated against each other every two weeks (that is, 2 weeks of echinacea followed by 2 weeks of goldenseal, and so on) starting 6-8 weeks before the onset of the cold and flu season in your area. Maximum dosage time should be no more than 6 months. Ginkgo bilboa: A stimulant herb that reportedly improves brain functioning by increasing blood flow to the brain. Aids in circulation, skin disorders and has a slight anti-depressant effect. Ginkgo has a cumulative effect and must be taken daily for at least two weeks before results are felt. Ginkgo works well in combination with Siberian ginseng during times of stress, or to boost a system worn out by illness. Any stimulant herb should be cycled. 2 weeks on/2 weeks off is the general recommendation, but it can also be 1 month on/1 month off, to a maximum of 6 months. However, we're all much better off to eat a balanced diet, get a good night's sleep, get plenty of fresh air and exercise, avoid stress, stressful situations and stressful people. This is where real health lies. :-) Marianne Southeastern Ontario AgCan zone 5b
