A stomachic medicine is one that serves to tone the stomach, improving its function and increasing appetite. While many herbal remedies claim stomachic effects, modern pharmacology does not have an equivalent term for this type of action.
Herbs with stomachic effects include:
- Avens, (Geum urbanum)
- Bitterwood, (Picraena excelsa)
- Colombo (herb), (Frasera carolinensis)
- Grewia asiatica (Phalsa or Falsa)
- Holy thistle
- Juniper berry
- Peach Bark
- White mustard seeds
- Rose hips
- Sweet Flag, (Acorus calamus)
- Wormwood, (Artemisia absinthium)
The purported stomachic mechanism of action of these substances is to stimulate the appetite by increasing the gastric secretions of the stomach, although the actual therapeutic value of some of these compounds is dubious. Some other important agents used are:
- Bitters: used to stimulate the taste buds, thus producing reflex secretion of gastric juices. Quassia, aristolochia, gentian, and chirata are commonly used.
- Alcohol: increases gastric secretion by direct action and also by the reflex stimulation of taste buds.
- Miscellaneous compounds: including insulin which increases the gastric secretion by producing hypoglycemia, and histamine, which produces direct stimulation of gastric glands.
