 3ss-ii, (2-8). 



PuVcis Kino Oompositua. Compound Powder of Kino. (B. P.) 

 (Pulv. cinnamon, 4 grs.; kino, 15 grs.; opium, 1 gr.) 

 Doae. — Dog, 1 powder; Foals and Calves, 4 powders. 



Administration. — Kino may be given in ball, powder, infusion (1-82), or 

 tincture. 



Action and Uses. — The physiological actions and therapeutics of 

 kino are nearly similar to those of catchu. The gum and pectin contained 

 in kino render its effect milder and more soothing to mucous membranes. 

 Aqueous solutions gelatinize on standing, on account of the gum in them. 

 The drug is prescribed chiefly in serous diarrhea, and also is occasionally 

 exhibited in dysentery and internal hemorrhages.

PREPARATIONS.

 evaporation, so that 1 mil= 1 Gm. of the crude drug. 

 Dose.—H. & C, §i-ii, (30-60); D., 3ss-ii, (2-8). 



Extractum Hama/melidis Liquidum. (B. P.) 

 Dose. — Same as fiuidextract. 



Aqua Samamelidis. 

 Takes place of the proprietary extracts and consists of the bark macerated 

 in water and distilled, alcohol being added to the distillate. 

 Dose. — Double that of fluidextract. 



Unguentum Hamamelidis. (B. P.) 



Action and Uses. — Hamamelis is apparently physiologically inert, as 

 shown by experiments on healthy animals. It nevertheless possesses con- 

 siderable medicinal virtue as an astringent and styptic. Witch-hazel is a 

 valuable agent, applied externally, to stop venous oozing in wounds, and 

 to reduce swelling and pain of bruises and sores. The fluidextract may 

 be diluted with 8, or less, parts of water, for these purposes; or the B. P. 

 ointment (1-10) may be employed. Internally hamamelis is useful in 

 diarrhea and mucous discharges. It arrests hemorrhage from the uterus, 

 kidneys, lungs and digestive tract; sometimes in a surprising manner. 

 The fluidextract is a successful hemostatic in bleeding from the bladder 

 or rectum (piles) when injected (1-8) into these parts. It lessens sore- 

 ness and swelling of blind piles — with an equal part of glycerin and a 

 little starch — and the same preparation is beneficial in eczema, pruritus, 

 and cutaneous irritations. The clear, colorless proprietary extracts — 

 now the aqua takes their place — are often more efficient externally and 

 internally (in the same doses) than the official fluidextract.
