A Quick Look at the Science


Horsetail, also known as equisetum arvense or puzzlegrass, is a medicinal herb that has 

been used by ancient herbalists for its health benefits for centuries. It has naturally occurring silica 

(an essential nutrient known for boosting hair and nail health), antioxidant 

properties, and aids with the formation of collagen.


Horsetail = Silica







What is Horsetail?


Horsetail is known for having the highest source of silica. Silica is the second most abundant element on earth and the third most abundant trace element in the human body - it is present in plants, animals, and humans. 


Aside from its silica properties, horsetail also contains flavonoids - powerful antioxidants with anti-inflammatory compounds and various health and anti-aging benefits.




Horsetail and Your Body


Similarly to collagen, our body’s level of silica decreases with age and actually plays a part in the biosynthesis of collagen production within our bodies. This decline in silica leads to signs of aging such as brittle hair and nails, aged skin, and a weaker immune system. That said, studies have found that is why silica holds various health and beauty benefits and is included as one of our Wholy Grail ingredients.







The Benefits of Horsetail


  • Skin
  • Hair
  • Nails
  • Immunity
  • Bones
  • Menstruation

- Boosts skin elasticity

- Tightens skin

- Improves overall skin texture

- Soothes inflammatory skin conditions 

- Aids with eczema, rosacea, redness in skin, and acne



Horsetail is rich in silica, a nutrient known to aid with collagen formation. Horsetail has anti-aging benefits and has been proven to increase skin elasticity, tighten the skin, and improve skin texture. Studies have also found that horsetail soothes skin and helps with skin conditions such as rashes, eczema, or acne due to its anti-inflammatory compounds. 

- Strengthens hair strands

- Reduces brittleness 

- Maintains hair tone and increases shine

- Improves hair texture 

- Reduces hair loss



Studies show that the Horsetail helps strengthen hair strands, reduce the brittleness of hair, maintain hair tone, improve hair texture, and can make hair appear shinier due to its naturally occurring silica compounds. Studies indicate that higher silica content in hair results in a lower rate of hair loss and an increase in brightness of hair. Furthermore, a clinical study found that those who took a silica supplement for 9 months showed more resistance to hair strand breakage compared to those who took a placebo. 

- Strengthens nail growth

- Reduces brittleness of nails 

- Decreases frequency of nails breaking



Our bodies’ silica levels decrease with age, which leads to having brittle nails. Horsetail has been found to improve nail brittleness due to its silica properties. According to research, silica improves nail fragility and overall nail health. 


- Contains high levels of anti-inflammatory properties

- Reduces oxidative stress

- Fights infections, aging, and diseases in the body 

- Reduces harmful toxins in the body



Studies have found that horsetail holds anti-inflammatory properties and can reduce oxidative stress – damage caused to our cells from having an imbalance of antioxidants and free radicals, which are compounds created in the body as a result of stress, pollution, poor diet, smoking, or alcohol. Research shows that oxidative stress can take a toll on our health, leading to sickness, inflammation, and may speed up the aging process. Horsetail helps support immune health by reducing inflammation and oxidative stress throughout the body.

- Strengthens bones

- Improves quality of bones



Horsetail is rich in silica, a nutrient known to support bone health. Science shows that horsetail helps regenerate bone tissue and improves overall bone health. Moreover, research has shown that silica can increase bone mass density and may help in reducing bone-related injuries. 

- Regulates irregular cycles

- Reduces excessive bleeding during menstruation 



Studies have shown that Horsetail, commonly used as a medicinal herb, can help regulate the menstruation cycle by combatting irregular cycles and reducing excessive bleeding during menstruation.
