Uses

Very useful in dropsy, nephritic and calculus affections, also in scrofula and syphilis. It is valuable as a diaphoretic and expectorant in pulmonary affections and used when Senega (Polygala senega) is not available. The British and American Physio-Medical associations relay the following: “For sluggishness of the liver with uric acid accumulation as follows: Boil l ounce each of Eryngo (Eryngium aquaticum) and Wild carrot (Daucus carota) in 1½ pints of water, reduced to 1 pint, tendon. সহজ বাংলা: মাংসপেশি/টেনডনে টান।" data-rx-term="strain" data-rx-definition="A strain is injury to a muscle or tendon. সহজ বাংলা: মাংসপেশি/টেনডনে টান।">strain, and take a wineglassful 4 times a day. In case of Jaundice take 1 ounce of Eryngo (Eryngium aquaticum), ½ ounce Barberry bark (Berberis vulgaris), boil in 1 quart of new milk for 10 minutes, strain and take 2 wineglassfuls every 3 hours. Most obstinate cases have been known to yield to this remedy in from 7 to 14 days.”

The pulverized root, in doses of 2–3 grains, is very effective in hemorrhoids and prolapsus, and 2 oz. of the pulverized root, added to 1 pint of good Holland gin, is effective in obstinate cases of gonorrhea, and gleet; to be administered in doses of 1–2 fl. drams three or four times a day. By some practitioners the root is employed as a specific in gonorrhea, gleet and leucorrhoea, used internally in syrup, decoctions, or tinctures, and the decoction applied locally by injection. Used externally and internally, it cures the bite of snakes and insects. Dose of the powder, from 20–40 grains; of the decoction, which is principally used, from 2–4 oz. several times a day.
