1976. Bliss, A. R. Proposed vegetable drug deletions. Jour. Amer. Pharm. Assoc. 9: 

 767-771. 1920. — A summarized report of answers received from 387 physicians of Atlanta, 

 Georgia, relative to the various vegetable drugs of the United States Pharmacopoeia, in 

 regard to their retention or deletion. Author gives a list of 31 drugs which more than 50 

 per cent of the physicians favored deleting. Another list of 30 received absolute unanimity 

 of opinion for retention. Comments by the author are included as to the necessity for the 

 deletion of such drugs as aconite on account of the dangers attending its use; squill, on ac- 

 count of its indesirable side actions; pepo, claimed to be absolutely worthless; and gelsemium, 

 which is of no great medicinal importance. Author presents a list of 22 drugs which might 

 well be deleted. The suggestion is offered to delete the crude drugs in case of aromatic oil 

 drugs and to retain their respective volatile oils. — Anton Hogstad, Jr.

1978. Grant, E. H. New tests for some purgative drugs. Jour. Amer. Pharm. Assoc. 

 9 : 763-766. 1920. — A series of new color tests for a number of purgative drugs, namely, 

 Scammony, Jalap, Leptandra, Gamboge, Podophyllum, Senna, Rhubarb, Butternut (bark 

 of root), Cassia Fistula, and Chionanthus. The tests given for Gamboge, Podophyllum, 

 Senna, Rhubarb and Chionanthus were found to be quite characteristic; the other tests while 

 being far from conclusive, are of value in assisting to identify these drugs. — Anton Hogstad, Jr. 



1979. Hoffstein, B. H. Notes on henna. Amer. Jour. Pharm. 92:543-547. 1920.— A 

 brief review of the historical usages of henna. Analysis of one of the so-called henna hair dyes 

 disclosed the following combination: powdered sumac, henna, ferrous sulphate, and copper 

 sulphate. Another sample was found to contain pyrogallol and henna in one container, and 

 a mixture of ammonium chloride and copper sulphate in the other. Attention is called to the 

 erroneous statement that henna does not contain tannin, which has been copied and recopied 

 from time to time. Method for the extraction of the tannin is given as follows: Extract 

 chlorophyll with ether; then percolate with 90 per cent alcohol; distil off the alcohol and again 

 exhaust the syrupy residue with ether; dissolve residue in 95 per cent alcohol and again distil 

 off alcohol. This method yields a resinoid tannin, which is soluble in hot water and capable, 

 like other tannins, of reacting with ferric salts and gelatine. — Anton Hogstad, Jr. 



1980. Kraemer, Henry. Michigan — An important source of raw vegetable products. 

 Michigan Acad. Sci. Ann. Rept. 21 : 167-199. 1919. — The author notes the influence of the 

 Great War on the supply of raw vegetable products, especially crude drugs in America, and 

 points out the desirability of cultivating many of the common medicinal plants in the United 

 States. A short account is given of efforts that have already been made along this line and 

 the obstacles to be overcome. One noteworthy success is mint oil culture in Michigan. 

 Michigan contains many wild medicinal plants and has a climate favorable to the cultivation 

 of many European drug plants. At the present time it has a greater acreage devoted to the 

 cultivation of medicinal plants than any other state. The author presents a summary of 

 recent experiments in the growing of medicinal plants at the University of Michigan botanical 

 gardens. About fifty different species were grown, with a total of 20,000 individual plants, 

 of which 15,000 were harvested, giving abundant material for tests. — H. T. Darlington.
