* [[Bromelain]] is a popular natural digestive aid due to it's ability to digest proteins. It's used for bloating, gas and other digestive symptoms and for conditions such as irritable bowel syndrome.
* Bitter herbs : Consuming "bitter" herbs just before a meal can help promote digestive secretions which, of course, aid in proper digestion. According to The Herb Companion, herbs like gentian (Gentiana lutea), barberry root (Berberis vulgaris), dandelion (Taraxacum officinale), and artichoke (Cynara scolymus) are all useful in helping to reduce gas, bloating, and other digestive discomfort associated with indigestion. To go along with this, fennel (Foeniculum vulgare), cardamom (Elettaria cardamomum), dill (Anethum graveolens), cumin (Cuminum cyminum), caraway (Carum carvi), and [[Lemon Balm]] (Melissa officinalis) all help warm up the digestive tract, which facilitates the easy digestion and passage of food through the digestive tract.
* [[Miso]] stimulates the secretion of digestive fluids in the stomach.
