ACTION AND USES OF TAB, OIL OF CADE AND PITCH. 



Externally, tar produces hypersemia, and, when rUbbed 

 continually into the skin, sometimes papules and pustules. 

 It is a stimulant, rubefacient, antiseptic and parasiticide 

 externally. Poisoning may follow the extensive application 

 of large quantities of tar over a denuded surface, or if it be 

 licked off the skin. Tar is mainly employed in veterinary 

 medicine on the skin, and is a valuable remedy to relieve 

 itching and as a local stimulant in chronic eczema (" grease "), 

 sometimes in moist eczema and erythema, psoriasis, pityri- 

 asis, pruritus, and lichen. It also destroys the parasites of 

 mange and ringworm. It is applied with fat, vaseline, soap 

 or alcohol, in the proportion of 1-2 to 10. The official oint- 

 ment (1-2), is generally appropriate in the above-mentioned 

 skin diseases, but may require dilution. The following 

 preparation is serviceable on patches of psoriasis : 



Tar, soft or green soap, each two ounces ; alcohol, two 

 ounces. Pure tar painted over the surface with a bru^h, is 

 often most efficient in obstinate cases of eruptive disorders.
