Description
Horsetail Herbal Teas 40g
Horsetail tea is made from Equisetum arvense, an ancient, fern-like perennial plant rich in minerals—particularly silica—and traditionally used for its wellness properties. A typical 40 g pouch offers multiple servings of this naturally caffeine-free herbal infusion. It’s commonly used to support hair, skin, and nail health, and may be helpful in managing incontinence or bedwetting in some contexts.
Benefits of Horsetail Tea
• Hair, Skin & Nail Support
Horsetail is valued for its high silica content, which is believed to contribute to stronger hair, nails, and skin.
• Bone Health
While still early in research, animal studies suggest horsetail may help support bone formation.
• Anti-Inflammatory & Antioxidant Effects
Compounds in horsetail may have antioxidant and anti-inflammatory properties, and may act as a mild diuretic to support fluid balance.
• Urinary Support
Traditionally used to help with mild incontinence and bedwetting—especially in herbalist circles and some product descriptions
Safety Considerations
-
Thiaminase activity
Horsetail contains thiaminase, which may decrease vitamin B₁ levels over time—potentially leading to deficiency. -
Electrolyte imbalance
Due to its mild diuretic effect, prolonged use may lower potassium levels. -
Interactions with medications
-
Lithium: May impair excretion, increasing lithium levels.
-
Diabetes meds: Could amplify blood sugar-lowering effects.
-
Diuretics: Combined use risks excessive potassium loss.
-
Efavirenz & NRTIs: May reduce effectiveness of certain HIV treatments.
-
-
Avoid in certain groups
-
Not recommended during pregnancy or breastfeeding.
-
Alcoholics (due to thiamine risk), those with hypokalemia, heart or kidney disease should avoid.
-
Potential allergies, including to carrots or nicotine (horsetail may contain trace nicotine).
-
-
Long-term use caution
Herbalists often advise intermittent use or breaks (e.g., cycles of a few weeks on, followed by breaks)
