23. I've bought marsh mallow root before, for medicinal purposes.

So, someone has to be farming it, if only for that

Here's some info on its uses that way:

Marsh Mallow

---Parts Used---Leaves, root and flowers. The leaves are picked in August, when the flowers are just coming into bloom. They should be stripped off singly and gathered only on a fine day, in the morning, after the dew has been dried off by the sun.

---Constituents---Marsh Mallow contains starch, mucilage, pectin, oil, sugar, asparagin, phosphate of lime, glutinous matter and cellulose.

---Medicinal Action and Uses---The great demulcent and emollient properties of Marsh Mallow make it useful in inflammation and irritation of the alimentary canal, and of the urinary and respiratory organs. The dry roots boiled in water give out half their weight of a gummy matter like starch. Decoctions of the plant, especially of the root, are very useful where the natural mucus has been abraded from the coats of the intestines, The decoction can be made by adding 5 pints of water to 1/4 lb. of dried root, boiling down to 3 pints and straining: it should not be made too thick and viscid. It is excellent in painful complaints of the urinary organs, exerting a relaxing effect upon the passages, as well as acting curatively. This decoction is also effective in curing bruises, sprains or any ache in the muscles or sinews. In haemorrhage from the urinary organs and in dysentery, it has been recommended to use the powdered root boiled in milk. The action of Marsh Mallow root upon the bowels is unaccompanied by any astringency.

Boiled in wine or milk, Marsh Mallow will relieve diseases of the chest, constituting a popular remedy for coughs, bronchitis, whooping-cough, etc., generally in combination with other remedies. It is frequently given in the form of a syrup, which is best adapted to infants and children.
