Horsetail has been used since antiquity for its diuretic properties. But it is also extremely useful in cases of cellulite, osteoporosis and for the wellbeing of nails and hair. The credit goes to its rich silicon content — its true strength.
The origins of horsetail are Asian, but the plant is widely distributed across Europe in damp meadows, fields and along watercourses. It owes its nickname, mare's tail, to the distinctive shape it takes on during the summer months.
Even in the time of Galen, horsetail was used for its medicinal properties — to stimulate diuresis, on even serious wounds that were slow to heal, and for severe intestinal complaints and dysentery.
Today it is frequently used as a diuretic in the presence of oedema of the lower limbs and in all situations where there is an alteration of the mechanisms that regulate fluid exchange at the level of the blood and lymphatic capillaries.
Horsetail is useful in cases of inflammation of the urinary tract, such as cystitis, prostatitis and urethritis, and is particularly indicated for those who suffer from nephritis. In the spring, when we begin our detoxification processes, this plant — considered an excellent kidney tonic — should not be overlooked.
But the characteristic that makes horsetail particularly interesting is its rich silicon content, in the form of silica, an element that plays a part in the bone calcification process, playing a guiding role in facilitating the deposition of calcium.
It is of significant value in cases of osteoporosis and when bone remineralisation is necessary. It is therefore excellent after fractures, trauma or following a prolonged period of rest or immobility. The benefit of administering horsetail in old age is clear, as it is in all cases of degenerative diseases.
Silicon also plays a role in the development of connective tissue, increasing its strength and thereby contributing to the integrity of articular cartilage and arterial walls. It is therefore recommended in cases of arteriosclerosis, osteoarthritis and delayed wound healing, including for topical use.
It is also used to keep nails and hair in good health: it is indeed found in many specific supplements.
Recent studies are bringing to light further properties and characteristics of horsetail in the cardiovascular field. The aim of the research is to evaluate its antiplatelet aggregation effects, which would place it among the natural remedies against hypertension.
Capsules or tablets, mother tincture or fresh plant juice are all easy to find. For herbal tea enthusiasts, we recommend a decoction made by slowly simmering the plant for around an hour and a half. This is the time needed to extract a good percentage of notably stable silica.
The mineral salts contained in horsetail powder stimulate collagen production, so it can be used externally as a skin elasticiser and toner, for the prevention of wrinkles or during a period of diet aimed at weight loss.
In this case, internal use is also recommended for its ability to reduce fluid retention and make its elimination easier, including in the presence of cellulite.
