TOXICITY AND SIDE EFFECTS

Mild side effects were reported, like nausea, headache and constipation, but no serious toxicity (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4220499/). You can have too much of a good thing and if you overdo this substance, you could interfere with thyroid hormones. The effect of arjuna when combined with drugs has not been well researched.

Research has shown in animal studies that arjuna provides a protective role in cardio health and ischemia.
