There are several fast-acting allopathic medicines for high cholesterol which get to work within a few days. But Himalaya Abana is an ayurvedic medicine, so it could take some time to show results, if it shows any at all. You may see improvements in your cholesterol levels a few weeks after consuming this medicine, but you might not.
Also, it’s claimed that Himalaya Abana does not cause any side effects as it is a herbal supplement. But that depends on your medical condition. And if you exceed the prescribed dosage or do not take it as advised by the doctor, it may cause some side effects.
