Sarpagandha significantly improves human health, primarily by calming the nervous system and lowering blood pressure. It works well for ailments like anxiety, sleeplessness, and some mental illnesses. However, if taken excessively or without the right advice, it can also have negative effects like sadness, drowsiness, or a slowed heart rate. As a result, even though it has advantages, it needs to be used carefully and under medical supervision.
