Cavalinha (HORSETAIL) Side Effects & Safety
Horsetail is POSSIBLY UNSAFE when taken by mouth long-term. It contains a chemical called thiaminase that breaks down the vitamin thiamine, possibly leading to thiamine deficiency. Some products are labeled "thiaminase-free," but there's not enough information available to know if these products are safe.
Special Precautions & Warnings:Pregnancy and breast-feeding: Not enough is known about the use of horsetail during pregnancy and breast-feeding. Stay on the safe side and avoid use.
Diabetes: Horsetail might lower blood sugar levels in people with diabetes. Watch for signs of low blood sugar (hypoglycemia) and monitor your blood sugar carefully if you have diabetes and use horsetail.
Low potassium levels (hypokalemia): Horsetail might flush potassium out of the body, possibly leading to potassium levels that are too low. Until more is known, use horsetail with caution if you are at risk for potassium deficiency.
Low thiamine levels (thiamine deficiency): There is a concern that horsetail could make thiamine deficiency worse.
Moderate Interaction Be cautious with this combination

This could increase how much lithium is in the body and result in serious side effects. Talk with your healthcare provider before using this product if you are taking lithium. Your lithium dose might need to be changed.
