Is expiry date of Ginseng really that crucial?

no, its not true. the expiration date is for when the medication is suppose to used by, or discarded. if a medication is way past the date i wouldn't recommend using it. if it was a couple days or a week past, there probably wouldn't be any harm in using it. the expiration date is for when the drugs desired effects are estimated to change and either become weaker or unsafe to take.

In the U.S., most otc medications have expiration dates based on how long the manufacturer has kept the product and tested it's efficacy and safety. Manufacturers have no reason to test for long periods of time because most people will discard an expired product.

no. the effect just might not be as strong. the expiration date is just an estimate
