I have been taking a liquid horsetail herb product for the last 2 years.
Q. Dear Terry, “I have been taking a liquid horsetail herb product for the last 2 years. Now, I've heard that you should not take horsetail long term. Can you advise me if I can continue this program?” — Rosemary E., Burlington, VT
A. Dear Rosemary, The horsetail (Equisetum arvense) plant is a great source of silica. However, I would not recommend taking it as an unfiltered, unstandardized liquid form as it can contain substances that may be harmful if taken long term.
I recommend looking for a highly purified extract obtained from the above-ground parts of the common horsetail (Equisetum arvense) plant. In a special process, the silica in the plant is extracted while still attached to the plant bioflavonoids that support its activity in the body. At the same time, all the harsh and potentially harmful substances are screened out using this gentle process. This unique botanical silica is then blended with a specific marine oil to enhance absorption, beneficial effects, and cell membrane penetration of the active compounds. This form of silica is extremely soluble and virtually 100% bioavailable for the body. I recommend taking 400-800 mg of the specialized, standardized horsetail extract twice daily.
