Dandelion Root Extract
Also known as: dandelion root extract, common dandelion, lion's tooth, face leaf, creeping dandelion, Taraxacum officinale root extract
Overview
Dandelion root extract is derived from the roots of the dandelion plant, scientifically known as Taraxacum officinale, a prevalent weed known for its diverse traditional medicinal applications. Historically, it has been leveraged for digestive health, liver and gallbladder support, and as a diuretic agent. The extract boasts a rich composition of phenolic compounds and flavonoids, imparting significant antioxidant and anti-inflammatory properties. While animal studies reveal potential advantages, such as inhibiting cancer cell growth, human clinical research remains limited, highlighting a need for more comprehensive studies. Additionally, traditional uses extend to stimulating appetite and enhancing digestive functions, marking it as a common herbal supplement notable since ancient times.
Benefits
Dandelion root extract is recognized for its various beneficial effects. Strong evidence supports its anti-cancer properties, particularly in inhibiting colorectal cancer cell proliferation without harming normal cells. Additionally, its diuretic effects contribute to increased urine output. The extract is also celebrated for its anti-inflammatory and antioxidant traits due to its phenolic content, enhancing liver and gallbladder health and possessing mild laxative effects. While promising outcomes primarily stem from animal and in vitro studies, the clinical relevance and exact effect sizes warrant further validation in human populations, particularly among cancer patients and those with digestive issues.
How it works
Dandelion root extract exerts its effects by modulating critical biological pathways. Its anti-cancer mechanisms involve regulating glycerophospholipid and unsaturated fatty acid metabolism, particularly through the inhibition of the CHKA enzyme and downregulating pathways like PI3K/AKT/SREBP/FADS2, which are crucial for cancer cell survival. Additionally, taraxasterol, a significant compound in dandelion, alleviates inflammation by curbing oxidative stress. The extract interacts with the digestive and urinary systems, fostering improved appetite and digestive health while increasing urine output due to its diuretic properties.
Side effects
Dandelion root extract is typically considered safe when consumed at traditional dosing levels, although empirical safety data is sparse. Common side effects are inadequately documented; however, allergic reactions, such as contact dermatitis, may occur in a minority of users. Drug interactions can be significant, especially with anticoagulants, certain antibiotics, lithium, and medication metabolized through the liver. The extract's high potassium content necessitates caution, particularly alongside potassium-sparing diuretics. Individuals with bleeding disorders should approach with care due to the potential for prolonged blood clotting. Caution is advised for pediatric use and during pregnancy or breastfeeding, where consultation with a healthcare provider is warranted.
Dosage
The ideal dosage for dandelion root extract is yet to be definitively established, as human studies do not offer formal recommendations. Suggested dosage ranges from animal studies vary, typically between 50-100 mg/kg body weight. Traditionally, dandelion roots or leaves can be prepared in forms such as teas, tinctures, or capsules, depending on individual preference. While no established maximum safe doses exist, long-term animal studies indicate that dosages up to 8 g/kg body weight appear safe. There are no specific timing or format requirements for consumption, and the absorption processes in humans necessitate further investigation.
FAQs
