Indications: Dandelion leaf is a very powerful diuretic, its action comparable to that of the drug `Frusemide'. The usual effect of a drug stimulating the kidney function is a loss of vital potassium from the body, which aggravates any cardio-vascular problem present. With Dandelion, however, we have one of the best natural sources of potassium. It thus makes an ideally balanced diuretic that may be used safely wherever such an action is needed, including in cases of water retention due to heart problems. As ahepatic & cholagogue Dandelion root may be used in inflammation and congestion of liver and gall-bladder. It is specific in cases of congestive jaundice. As part of a wider treatment for muscular rheumatism it can be most effective. This herb is a most valuable general tonic and perhaps the best widely applicable diuretic and liver tonic. Ellingwood recommends the root for the following patholgies: chronic jaundice, auto-intoxication, rheumatism, blood disorders, chronic skin eruptions, chronic gastritis, aphthous ulcers.
Combinations: For liver and gall-bladder problems it may be used with Barberry or Balmony. For water retention it may be used with Couchgrass or Yarrow.
Preparations & Dosage: Decoction: put 2-3 teaspoonfuls of the root into one cup of water, bring to boil and gently simmer for l0-l5 minutes. This should be drunk three times a day. The leaves may be eaten raw in salads. Tincture: take 5-l0 ml of the tincture three times a day.
