Canadian Bitters®

What Are Bitters?

Bitters stimulate and tonify the digestive apparatus in preparation for mealtime, providing an aid to people who have trouble with dyspepsia—gas, burping, bloating, and indigestion. The use of herbal bitters has been an integral part of almost every cultural tradition in the world. In the early 16th century, for example, Venetian monk Dom Bernardo Vincelli invented the aperitif we know as Benedictine. It started as an ‘elixir’ to revive tired Benedictine monks and was also claimed to cure malaria.1

Bitters and The Perennial Wisdom of Ayurveda

Optimize Your Agni

Ancient Ayurveda agrees with modern Naturopathy, which holds that loss of digestive fire—“Agni” in Ayurveda—is a factor that plays a role in the onset of all diseases.2,3

Bitters act indirectly as tonics to the whole system, gentian being the quintessential digestive bitter. According to the Eclectics, who formed a prominent and distinctive school of American medicine in the 19th and early 20th centuries, relying heavily on botanical remedies for their healing practices, gentian is best used “where the powers of life are depressed and recovery depends upon (the) ability to assimilate food.”.4

Ayurveda holds that “all metabolic processes” are dependent on healthy Agni.5 Thus, among other things, diminished Agni is a root cause of weakness, fatigue, and the accumulation of waste products in the body.

“Bitters Deficiency Syndrome”

This is a term used by Michigan herbalist Jim McDonald to highlight the importance he places on bitters. Quoting James Green (The Male Herbal), McDonald suggests bitters deficiency as a major factor in not only digestive issues but also hormone and metabolic imbalances, migraine headache, liver and gall bladder dysfunction, diabetes, and numerous other conditions. He suggests that bitters are especially effective for conditions as disparate as PMS, bad breath, moodiness, sluggish metabolism, addictions, anxiety, and depression!.6

The Problem With Laxative-Heavy Formulas

Canadian Bitters® does not contain stimulant laxatives like aloe, senna, and rhubarb, which are typically contained in Swedish Bitters formulas. Such herbs make the latter habit-forming, meaning that they should not be used for more than 10-14 days.

An Energetically Balanced Formula

Canadian Bitters® contains what are considered cooling (bitter) and warming (pungent) herbs, as well as aromatic digestives. Pungent, warming herbs like ginger and turmeric are counterbalanced by cooling bitters like gentian (“unrivalled as a stomachic tonic,” as British herbalist Mrs. Maude Grieve puts it.7) and dandelion. Cardamom, meanwhile, is an aromatic digestive, especially effective for colic and flatulence.


Gentian is the key bitter herb on which this formula is hinged. A recent significant review study that examines the physiological mechanics of bitters concludes that this herb works through bitters receptors in the digestive tract rather than exclusively in the mouth through taste. It is concluded that the cephalic (i.e. affecting the brain) responses initiated by gentian change gastric phase haemodynamics by supporting postprandial hyperaemia (i.e. increased blood flow and tonus in the vasculature), as well as sustaining systemic blood pressure. Gentian is in fact eupeptic, which is to say that it is a balancing agent and has no effect on those with normal digestion.8
