Horsetail
Horsetail is a mineral-rich plant traditionally used for mild diuretic support and for hair/skin/nail routines due to its silica content. It’s best used short-term and from reputable sources, because improper products can include compounds (like thiaminase) that may be problematic with long-term heavy use.
Key Benefits
- Provides silica and minerals supportive of hair/skin/nail routines (nutrition-adjacent)
- Mild diuretic effect may support fluid balance short-term
- Traditionally used for urinary wellness support
- Often used in ‘strengthening’ blends with nettle or oatstraw
Common Issues It May Help With
- Brittle nails (supportive)
- Low mineral intake (diet support)
- Mild water retention
- Urinary wellness support (supportive)
How To Use (Simple)
- Tea: simmer (decoct) 1–2 tsp dried herb in water for 10–15 minutes
- strain. Use short-term. Tincture/capsules: follow label directions. Ensure adequate hydration.
Taste / Notes
Mild, grassy, slightly mineral.
Evidence Level
Traditional use plus some evidence for mild diuretic action; hair/nail claims are mostly supportive and nutrition-based.
Cautions
Avoid long-term daily high-dose use. Use caution if you have kidney disease. Avoid during pregnancy/breastfeeding due to limited data. If product is not properly processed, thiaminase risk is a concern—choose reputable suppliers.
Interactions
Use caution with diuretic medications (additive effects) If on lithium, avoid diuretic herbs unless clinician-guided (lithium levels can shift) If you take thiamine-sensitive medications or have malnutrition risk, avoid long-term heavy use
