 Chrysantiia, Michx. Pumila, Linn., (Evening Primrose, Cure- 

 all, etc.). The Biennis is chiefly used in medicine. Bark and 

 leaves mucilaginous, slightly acrid. Dr. Griffith states that he has 

 cured infantile eruptions, as tetter, with a decoction of this plant, when 

 all other means had failed. (Med. Bot. p. 304.) He directs a strong 

 decoction, with which the parts affected are to be bathed several times 

 a day. Forms a good emollient in ulcers. 



Lythrum Hyssopifolia, Linn., (Common Purple Loose Strife). 

 The whol*e plant demulcent and astringent; useful in diarrhoea and 

 chronic dysentery. Decoction of the root ( 5 i- to O. j.) the»best/orm of 

 exhibition, in doses of 5 ij., three times a day. A useful remedy.

 vesicant.

 Lacustre, (Swamp Gooseberry). Floridum, (Wild Black Currant). 

 Prostratum, (Fetid Currant). Currant juice is laxative, refrigerant 

 and antiseptic. Its wine contains 20 per cent, of alcohol. The black 

 currant is astringent. 



Saxifragace.e. — (The Saxifrage Tribe.) 



Heuchera Americana, (Common Alum Root). A powerful astrin- 

 gent. An extract from the roots of this plant, would probably be equal 

 to that of the Rhatany or Catechu. The basis of some of the cancer 

 powders of empirics. Employed by the Indians as an application 

 to wounds and ulcers. 



HamamelacejE, R. Brown. — (Witch Hazel Tribe.) 



Hamamelis Virginica, Linn., (Witch Hazel). The bark of this 

 plant has a bitter, astringent, somewhat sweetish and pungent taste. Is 

 employed by the Indians as a sedative and discutient to painful tumors, 

 and external inflammations. It is a popular remedy in the shape of 

 a poultice or decoction, in hemorrhoidal and ophthalmic affections ; also 

 infusion of leaves in bowel complaints and hemorrhages. Seeds are 

 edible, like the hazelnut. Deserves further trials. Erroneously sup- 

 posed to have the power of indicating water and ores.
