Bao He Wan (Harmony-Preserving Pill) bǎo hé wán · 保和丸

Safety. This is a formula for a traditionally described food-retention pattern, not a digestive tonic and not a weight-management product; using it as an everyday aid after large meals is one of the more common misuses of a classical formula, and anyone with unintentional weight loss, persistent indigestion or difficulty swallowing needs conventional assessment first. Medicated leaven (神曲) is a fermented product usually made on a wheat or flour base, which matters for coeliac disease and wheat allergy, and a badly made ferment is also the route by which mould contaminants enter a herbal product, so sourcing is not a detail. Hawthorn is acidic and can aggravate reflux or an irritated stomach, and it has documented cardiovascular activity that is a reason for caution alongside heart medicines. Radish seed (莱菔子) is classically recorded as reducing the action of ginseng, so the two are not taken together in traditional practice. Pinellia must be processed (法半夏 or 姜半夏); raw pinellia is toxic and irritant and is not taken by mouth. Forsythia is cooling and can loosen the stool. Amounts are deliberately not given here.
