PHARMACAL PLANTS AND THEIR CULTURE. 
Between 1881 and 1885 the State of Colorado paid out nearly $200,000 
in bounties to eradicate the weed. 
The poisonous principle has been studied, however, with unsatisfac- 
tory results. An acid (loco acid) has been isolated, to which the 
poisonous properties are attributed. Requires further careful study. 
150. Atriplex species. Chenopodiacece. 
Used as food and medicinally by Indians and Mexicans. They are 
rich in impure soda. (Palmer Proc. A. Pli. A. 27 : 153, 1879.) 
151. Atriplex hortensis. Chenopodiacece. 
Very rich in sodium and other salts. Used as food and for medic- 
inal purposes by Indians and settlers. 
152. Atropa belladonna L. Deadly nightshade. Solanacece. 
This plant thrives well in the United States, where it is grown as 
an ornamental plant, and experimentally and commercially in several 
places. The firm of Johnson and Johnson of New Brunswick, N. J., 
manufacturers of belladonna plasters, have grown belladonna experi- 
mentally for a number of years. The experiments are now being con- 
tinued in California (Castro Valley, near Hayward, and elsewhere). 
(King’s Dispensatory, 18th ed., p. 332.) Leaves and roots are used, 
which should not be collected from first-year plants. Collect from 
plants two or four years old, at the time of flowering. Price of roots 
and leaves per pound, about 12 cents wholesale. English belladonna 
is much more valuable than German belladonna. All parts of the 
plant are poisonous ; used as a nerve sedative, diuretic, in catarrhs, 
in ophthalmology, in the manufacture of plasters and ointments. 
Said to be a preventive and cure of scarlatina (homeopaths), checks 
secretions, dilates pupil (mydriatic), used in asthma, phthisis, to relax 
sphincter muscles, to relieve strangulated hernia, etc. (See, also, 
The Pharmaceutical Era, June 9, 1904, p. 556, Pacific Druggist, 1905, 
and Pacific Pharmacist, 1907.) For the comparative value of wild 
and cultured belladonna, see Proc. A. Ph. A. 30 : 162. 1882. 
153. Aurantium dulcis L. varieties. Oranges. Aurantiacece. 
Extensively cultivated in the State. Other members of the family 
are cultivated in the State, to say nothing of the remarkable crosses 
between oranges and related fruits, as the tanglo, mandarin, pomelo, 
navel oranges, etc. 
154. Baccharis glutinosa Pers. Asteroidece. 
A decoction of the leaves is used as an eyewash by the Coahilla 
Indians. (Barrows.)
