Friedrich A. Flückiger, Pharmacographia (1879)
“ Uses—A decoction of the seeds (1 p. to 70 p. of water) is employed in India as a cooling, demulcent drink. The seeds powdered and mixed with sugar, or made gelatinous with water, are sometimes given in chronic diarrhœa. POLYGONACEÆ. RADIX RHEI. Rhubarb; F. Rhubarbe; G. Rhabarber.Botanical Origin—No competent observer, as far as we know, has ever ascertained as an eye-witness the species of Rheum which affords the commercial rhubarb. Rheum officinale, from which it seems, at least partly, derived is the only species yielding a rootstock which agrees with the drug. ”
