Note 528 — Chapter XXVIII

"Attacked with violent tertian ague, and without any medicine, in Pampa-yacu, I made use of the green bark direct from the chinchona-tree, which I peeled from one growing a few hundred steps distant; and although, in consequence of unavoidable exposure in the rainy season, and the very great exhaustion after eight months' wild forest life, the disease returned on three occasions, it was each time conquered within a week. The very unpleasant additional effect, in this case, of the green bark, of producing obstinate obstructions, demands consideration. It might be well obviated by a plentiful addition of Epsom salts to the infusion. After the first dose of this fresh and unadulterated remedy, a sensation of general well-being is felt, and after recovery, on the first excursion, one approaches the healing trees with warm feelings of gratitude, whose beautiful reddish blossoms appear in such quantities in January, and their round crowns can be distinguished at a distance."—Poeppig, Reise, ii. p. 223.
