It is not safe to consume Bhoonimbadi Kada once it is past its expiry date, even if the bottle is unopened, because after expiry the manufacturer cannot guarantee its potency, purity, or safety, and herbal formulations may degrade or develop harmful byproducts over time; the best guideline is to discard the expired product and obtain a fresh, unexpired supply if your doctor or Ayurvedic practitioner recommends its use.
