This supplement has been used in connection with the following health conditions:

Used for Why
1 Star
Indigestion, Heartburn, and Low Stomach Acidity
Refer to label instructions
Blessed thistle acts as a digestive stimulant and may be helpful for indigestion.

Bitter herbs are thought to stimulate digestive function by increasing saliva production and promoting both stomach acid and digestive enzyme production. As a result, they are particularly used when there is low stomach acid but not in heartburn (where too much stomach acid could initially exacerbate the situation). These herbs literally taste bitter. Some examples of bitter herbs include greater celandine, wormwood, gentian,dandelion, , yarrow, devil’s claw, bitter orange, bitter melon, juniper, andrographis, prickly ash, and centaury.. Bitters are generally taken either by mixing 1–3 ml tincture into water and sipping slowly 10–30 minutes before eating, or by making tea, which is also sipped slowly before eating.

1 Star
Poor Digestion
Refer to label instructions
Folk medicine used blessed thistle tea for digestive problems, including gas, constipation, and stomach upset.
Folk medicine used blessed thistle tea for digestive problems, including gas, constipation, and stomach upset. Certain compounds, sesquiterpene lactones, such as cnicin, provide the main beneficial effects of blessed thistle in the treatment of indigestion. The bitterness of these compounds stimulates digestive activity, including the flow of saliva and secretion of gastric juice, which leads to improved appetite and digestion.

Traditional Use (May Not Be Supported by Scientific Studies)

Folk medicine used blessed thistle tea for digestive problems, including gas, constipation, and stomach upset. This herb was also used—like its well-known relative, milk thistle1—for liver and gallbladder diseases.

How It Works

Botanical names:
Cnicus benedictus

How It Works

The sesquiterpene lactones, such as cnicin, provide the main beneficial effects of blessed thistle in the treatment of indigestion. The bitterness of these compounds stimulates digestive activity, including the flow of saliva and secretion of gastric juice, which leads to improved appetite and digestion.2 Some pharmacological evidence suggests that blessed thistle may also have anti-inflammatory properties.3

How to Use It

The German Commission E monograph recommends 4–6 grams of blessed thistle per day.4 Alternatively, tincture (1/2 teaspoon [2 ml] three times per day) may be used. Approximately 1/2 teaspoon (2 grams) of the dried herb can also be added to 1 cup (250 ml) of boiling water and steeped 10 to 15 minutes to make a tea. Three cups can be drunk each day.
