Common plumb(Prunus domestcia)

 

 

The dried fruit, known as prunes, is a safe and effective laxative and is also stomachic.

The bark is sometimes used as a febrifuge.

Although no specific mention has been seen for this species, all members of the genus contain amygdalin and prunasin, substances which break down in water to form hydrocyanic acid (cyanide or prussic acid). In small amounts this exceedingly poisonous compound stimulates respiration, improves digestion and gives a sense of well-being.
