NOTE: These indications are only for use with embryonic plant stem cell tissues. Adult plants do not have the same constituents, actions or applications in most cases.

The Equisetum arvense is a small perennial with horizontal stems. It is native to the Northern Hemisphere and is known to be a stubborn and unwelcome visitor in many garden beds. Its extensive, creeping root system goes deep into the soil, spreading new shoots periodically, making it extremely difficult to eradicate. Its leafless, fertile stems are light brown and are about 18 inches high, with a spore-bearing cone on top. Conspicuous sheaths give these stems a rather jointed appearance. The wintertime leaf and flower buds are close to an inch long and are covered with a sticky gum that is melted by the first warming rays of spring.

The Equisetum arvense has been used for scrubbing pans and polishing pewter, brass, and copper. The ribbed and furrowed stem cells of this plant have a high percentage of silica that gives it an abrasive touch, hence its name Equisetum, derived from the Latin roots equus, meaning “horse” and seta, meaning “bristle.”

No other herb in the entire plant kingdom is as rich in silicon as is horsetail. This trace element really helps to bind protein molecules together in the blood vessels and connective tissues. Silicon is the material of which collagen is made. Collagen is the “body glue” that holds our skin and muscle tissues together. Silicon also promotes the growth and stability of the skeletal structure. Research suggests that silicone helps prevent osteoporosis, and horsetail is among the richest plant sources of this mineral which the body can readily use.

Horsetail is that kind of rare and unique cosmetic agent which beautifies from the inside out rather than just externally. Mature skin or skin that shows signs of premature aging may fall into this category. Horsetail improves the texture and tone of hair, nails and skin and greatly strengthens bones and teeth.




Greatly strengthens teeth. Jaw bone loss.

Warning: Do not use horsetail if you are taking digoxin or digitalis. The diuretic effects of horsetail may cause Potassium loss, dangerously increasing the risk of toxicity associated with Digoxin and Digitalis (Do not take with Hawthorn), Lithium.

Contraindications: Chronic ingestion of this herb can decrease the level of thiamin or B1 due to thiaminase content. Beriberi is the sign of chronic toxicity. With the young shoots, and the smaller amount needed, it reduces this risk tremendously. Large doses of horsetail may cause symptoms of nicotine overdose, including fever, cold hands and feet, abnormal heart rate, difficulty walking, muscle weakness and weight loss. People who smoke or who use nicotine patches or nicotine gum should avoid horsetail. None of these contraindications has been observed in the embryonic form at a dose of even 10 drops 3 x a day.
