Hydrastis Canadensis. (Golden Seal.)

Botanical name: 

I will give the Hydrastis a brief notice, as it is in such general use for all the purposes of a tonic, that my readers know as much about it as I do. It improves the appetite and facilitates digestion; but beyond this it relieves gastro-intestinal irritation.

Its topical action, wherever applied, is that of a tonic, strengthening the circulation and nutrition. It is in common use for these purposes in diseases of the skin, diseases of the eyes, and diseases of mucous surfaces.

As a stomachic and tonic, I like the action of the finely powdered root, as well as the more costly preparations. Indeed, in most cases, I would prefer this, in equal quantity, to the Hydrastine.

A tincture made with Alcohol of 30° will be found a good preparation. It is more convenient for carrying, and added to water, gives a pleasant stomachic. A very good prescription would be Rx Tincture of Hydrastis, ʒij.; Tincture of Nux Vomica, gtts. xx.; Water, ℥iv. A teaspoonful every three or four hours.

The Sulphate of Hydrastia is (when properly made) soluble in water in the proportion of four grains to the ounce. It makes a valuable collyrium in chronic conjunctivitis, or the latter stages of the acute. It is also an admirable injection in the second stages of gonorrhoea, and in gleet.
