Effects of golden seal
The plant causes the constriction of the capillaries, which gives virtues to curb the hemorrhages. However, overdosage can cause hypertension as a side effect.
In therapeutic doses, golden seal can lower blood pressure or alter heart rate, so it should not be taken by people with heart disease.
Continued use depletes the intestinal flora, as it is a strong antiseptic and destroys healthy intestinal bacteria. This can lead to digestive problems such as vomiting, belly swelling and malabsorption of nutrients.
