Tumours of a simple nature, and sprains, may be usefully rubbed with Linseed oil; and another principal service to which the oil is put is for mixing the paints of artists. To make Linseed tea, wash two ounces of Linseed by putting them into a small strainer, and pouring cold water through it; then pare off as thinly as possible the yellow rind of half a lemon; to the Linseed and lemon rind add a quart of cold water, [204] and allow them to simmer over the fire for an hour-and-a-half; strain away the seeds, and to each half-pint of the tea add a teaspoonful of sugar, or sugar candy, with some lemon juice, in the proportion of the juice of one lemon to each pint of tea. The seeds afford but little actual nourishment, and are difficult of digestion; they provoke troublesome flatulence, though sometimes used fraudulently for adulterating pepper. Flax seed has been mixed with corn for making bread, but it proved indigestible and hurtful to the stomach. In the sixteenth century during a scarcity of wheat, the inhabitants of Middleburgh had recourse to Linseed for making cakes, but the death of many citizens was caused thereby, it bringing about in those who partook of the cakes dreadful swellings on the body and face. There is an Act of Parliament still in force which forbids the steeping of Flax in rivers, or any waters which cattle are accustomed to drink, as it is found to communicate a poison destructive to cattle and to the fish inhabiting such waters. In Dundee a hank of yarn is worn round the loins as a cure for lumbago, and girls may be seen with a single thread of yarn round the head as an infallible specific for tic douloureux. The Purging Flax (_Linum catharticum_), or Mill Mountain (_Kamailinon_), or Ground Flax, is a variety of the Flax common on our heaths and pastures, being called also Fairy Flax from its delicacy, and Dwarf Flax. It contains a resinous, purgative principle, and is known to country folk as a safe, active purge. They infuse the herb in water, which they afterwards take medicinally. Also a tincture is made (H.) from the entire fresh plant, which may be given curatively for frequent, wattery, painless diarrhoea, two or three [205] drops for a dose with water every hour or two until the flux is stayed.
