Amygdala Amara

Bitter almond. Rosaceoe.

According to Wohler and Liebig, the hydrocyanic acid formerly supposed to be contained in the almond, is the result of the reaction of water on amygdalin, the characteristic constituent of bitter almonds.

The bitter almond is used for flavoring, and peach kernels and cherry seeds, which have similar properties, are often substituted.

The observations of Org, made in 1822, hardly deserving to be called a proving, were published in 1825. Regarding his trustworthiness, see British Quart., XVI, 693. These were added to a collection of symptoms from the Laurocerasus, the Aqua laurocerasus, and Hydrocyanic acid, and printed in Hartlanb's Mat. Med., in 1828. In 1844 they were printed separately in Oak and Trink's Handbuch, with the addition of some toxic symptoms. Allen's Encyclopedia contains all, and a carefully made, almost complete, collection of poisonings. We only miss Gazin, Traite Pratique, 1853. The experiments of Douglas Maclacan are with a different preparation.
