Copy and Pasted from Web MD:

Horsetail refers to various plant species of the Equisetum genus. It may help reduce fluid retention, but might cause vitamin B1 deficiency when used long-term.

The chemicals in horsetail might have antioxidant and anti-inflammatory effects. They might also work like "water pills" (diuretics) and increase urination.

People use horsetail for fluid retention, urinary tract infections (UTIs), osteoporosis, loss of bladder control, and many other conditions, but there is "no" good scientific evidence to support these uses.

The article had pages of info and said that there are "many" conditions, supplements, and prescription drugs, that this horsetail tea is "not" safe for use with.

Pam can I asked what supplements you want ale for inflammation and osteoporosis?

? Is it?

Thank you
