Dandelion is a well-known plant that grows in temperate climates. This plant has been used in traditional practices for centuries. In addition to their medicinal properties, young dandelion leaves can be used in salads.
Direction of use
Few serious studies have been conducted to assess dandelion's usefulness. Taraxacin, a compound found in dandelion, appears to have a beneficial impact on digestion. The bitter compounds found in the root may be responsible for an increase in bile flow and potentially beneficial effects on the digestive system. Dandelion may have mild laxative and anti-inflammatory properties. Dandelion extracts may have diuretic properties in animals. In addition, dandelion is a source of vitamins and minerals, apparently rich in potassium, iron, calcium and vitamin A.
- Side effects
Dandelion is usually considered to be safe when used as a food or for therapeutic reasons. Acidity, gastric irritation and contact dermatitis are among the most frequent adverse effects observed with dandelion.
People who are allergic to plants from the Asteraceae/Compositae family can be allergic to dandelion. In addition, the latex found in the stem can cause skin allergies. People with gallbladder stone or with a bile flow disorder should not take dandelion.
- Pregnancy and breastfeeding
Pregnant women can safely eat dandelion but should not use it for medicinal purposes.
Dandelion interacts with some prescription drugs. People who wish to take dandelion should talk to their pharmacist first and always be vigilant.
In 2004, Canada adopted new regulations that control the manufacturing, packaging, labeling and importing of natural health products. The new regulations also include an adverse reaction reporting system. Products that conform to the regulation's criteria are identified with a natural product number (NPN) and can be legally sold in Canada. This number indicates that the product meets specific criteria for safety and purity, not that it is effective for any indication.
Medicinal plant contents vary naturally from plant to plant - just as fruits from the same package may vary in taste and texture. There is no standard to measure the active content of each plant. Thus, efficacy of natural products should be expected to vary from brand to brand as well as from bottle to bottle of the same brand.
