Dandelion Leaf vs. Kořen pampelišky
There are some differences in the chemical makeup between dandelion leaves and roots.
Both the leaf and root of dandelion are used medicinally due to their concentrations of various beneficial phytonutrients (rostlinné chemikálie).
Dandelion leaf and root both contain good amounts of vitamins A, B6, B12, C, D and K. They also contain minerals like magnesium, draselný, calcium and zinc.
Podle komplexní databáze přírodní léky (NMCD), dandelion leaf contains quercetin, luteolin, p-hydroxyphenylacetic acid, germacranolide acids, kyselina chlorogenová, chicoric acid, and monocaffeyltartaric acid. It also contains scopoletin, aesculetin, aesculin, cichoriin, arnidiol, and faradiol.
Dandelion root contains certain plant chemicals that the leaf does not, most notably including concentrated amounts of a polysaccharide called inulin. Others include taraxacoside, taraxasterol and caffeic acid. [1]
Some people use dandelion leaf as a laxative. Podle Dr.. Edward F Group, the leaf contains high amounts of kynurenic acid. This is a natural byproduct that results in the human body from metabolizing the amino acid L-tryptophan.
Kynurenic acid influences various digestive processes in the body. One of its well-documented effects is as a choleretic, which means it increases the production of bile as well as its transportation to the gallbladder. [2]
Bile contains bile acids which are important for digestion, nutrient absorption and neutralization of certain toxins. Bile increases the absorption of fatty acids and is integral for the assimilation of fat-soluble vitamins like vitamins A, D, E, a K.
Dandelion Leaf Health Benefits
Chemical analysis of dandelion leaf shows that it contains various active constituents including alkaloids, triterpenoids and natural plant steroids. [3]
Dandelion leaf is a good source for beneficial antioxidants which may protect the body from damage caused by oxidative particles and free radical molecules. [4]
Preliminary research in mice suggests that dandelion leaf may support hepatic (játra) funkce. A 2013 research study showed that administration of a leaf extract helped to:
- Promote healthy blood lipid (tuky) profiles;
- Suppress hepatic fat accumulation;
- Reduce resistance to insulin;
The mechanism of action involved is not yet well understood and it is not clear whether these effects will occur in humans. Nicméně, the effects have been attributed to dandelion’s antioxidant properties. [5]
Dandelion may also support liver function and detoxification by increasing bile production, promoting toxin excretion, improving fat metabolism and helping the body utilize available nutrients more efficiently. [6]
There is very limited research into the effects of dandelion on human subjects. Nearly all studies that have been completed have involved animal subjects.
Dandelion is not approved by the FDA as a medicine for the prevention or treatment of any disease or illness.
Dandelion Leaf Tea Medicinal Uses
Dandelion teas are sometimes promoted for weight loss and dieting. Nicméně, there is no research available to determine whether this herb works for weight loss.
One of the ways it may work is by increasing the excretion of water from the body. While this will temporarily result in a lower number on the scale, it will not actually result in changes to body composition or fat mass.
Many people use prescription diuretics (prášky na odvodnění) to help them shed excessive water weight and fluid accumulations.
These types of drugs are commonly prescribed to treat high blood pressure and heart disease. They are also used to treat some types of liver and kidney dysfunction as well as edema.
Dandelion leaf tea and supplements are used as natural water pills to promote diuresis (production of more urine in the kidneys). This may improve bloating and excessive swelling or inflammation.
V jedné studii lidské, all subjects experienced increased urine volume and urination frequency after taking a liquid dandelion extract. Based on results from this study, “T. officinale ethanolic extract shows promise as a diuretic in humans.” [7]
Dandelion seems to stimulate the kidneys to remove accumulated liquids from the body via urination. Increased urination helps the body to rid itself of toxin accumulations.
This may also improve urinary tract health and could help to prevent or reduce Urinary tract infections (Infekce močových cest). A combination of dandelion root with anti-bacterial uva ursi leaf extract has been shown to reduce the recurrence of UTI in females.
Dandelion Leaf Pregnancy Test
Jedním z traditional uses of dandelion leaf is to determine pregnancy. Nicméně, the validity of this test has not been established by research. It should not be relied upon as a conclusive test.
According to folklore medicine, the process of performing this test is as follows:
- Place dandelion leaf in a clean container.
- Saturate the leaf with fresh urine.
- Allow the urine to mix with the leaf for at least 10 minut.
If the dandelion leaf begins to display red “puchýře”, then you may be pregnant according to traditional herbal medicine sources.
Positive or negative results on test are not definitive. If you believe you may be pregnant, it is important to make an appointment with a doctor to perform a test and evaluation.
