Medicinal Properties 
Oesterlen, 39 in 1853, states that the powdered seeds were given 
for diarrhoea and similar complaints by Ritchie in the dose of one 
drachm per diem (Ed. Journ., May, 1852). Dorvault 40 says that 
guarana was introduced as a tonic and astringent, which is the use 
made of it in Brazil, and that it has been advocated as a remedy for 
neuralgia and migraine. A dose of 4 to 8 grammes was given, and 
there was a stock of it in the French pharmacies in 1867, when it was 
made into two syrups, tincture, pills, ointment and a chocolate. 
Chernoviz 41 mentions that guarana is prescribed as medicine in various 
affections, chiefly in diarrhoea and dysenteries, in doses of two drachms 
in eight ounces of water. Speaking of guarana in 1872, a writer in 
the Year Book of Pharmacy 42 says:—‘This drug is now attracting 
attention as a remedy for sick headache. It has been long known, 
but has never come into general use.’ Mr. Harold Wyatt, who has 
, ad some gears’ training in French pharmacy, tells me that the drug 
is more used in France than in England, and my own experience of 
t le two countries proves the same, as since 1884 I have seen guarana 
p scribed but three times, in cachets, and two of these occasions were 
whilst I was in France, but it appears that the elixir is sold to a 
si era le extent in Liverpool. Guarana is official in the pharnia-
