Horsetail: complete India guide

India has one of the highest rates of micronutrient deficiency in the world — and the supplement market is growing fast to meet it. But with hundreds of products on Amazon.in and little regulation, knowing what to actually buy is harder than it should be. This guide covers Horsetail from first principles: what it is, what the evidence says, and how to use it safely in an Indian context.

What is Horsetail?

Horsetail (Equisetum arvense) is an ancient plant that is one of the richest herbal sources of silica (silicon dioxide).

Horsetail is relevant for anyone dealing with hair-loss. It primarily acts on the hair.

How does Horsetail work?

Horsetail contains 5–8% silica by weight, mostly as insoluble silicon dioxide. Theoretically, silica supports

Who should take Horsetail?

Always consult your doctor before starting any new supplement, particularly if you are on prescription medication or have an existing health condition.

How to combine Horsetail

Buying guide for India

When shopping on Amazon.in, prioritise products that clearly state:

• The standardised active compound percentage
• Third-party testing (NSF, USP, or Informed Sport)
• The form of Horsetail (extract vs whole herb vs isolate)
• Vegetarian capsule certification if that matters to you

Generic “natural” or “herbal” labels without standardisation information are a red flag. The price difference between a well-made and a poorly-made Horsetail supplement is often small — the difference in efficacy is not.

Bottom line

Horsetail has Key citations: PMID 28085277 (Mimica-Dukic 2008, silica bone study), PMID 12596850 (Dressler 2016, h for hair-loss. Used consistently at the right dose, it is a reasonable addition to a wellness protocol for those dealing with these concerns.
