Cultivation | Propagation | General Uses Medicinal | Edible Uses Latin Name: Malus sylvestris Common Name: Crab apple Family: Rosaceae Author: Mill. Known Hazards: All members of this genus contain the toxin hydrogen cyanide in their seeds and possibly also in their leaves, but not in their fruits. Hydrogen cyanide is the substance that gives almonds their characteristic taste but it should only be consumed in very small quantities. Apple seeds do not normally contain very high quantities of hydrogen cyanide but, even so, should not be consumed in very large quantities. In small quantities, hydrogen cyanide has been shown to stimulate respiration and improve digestion, it is also claimed to be of benefit in the treatment of cancer. In excess, however, it can cause respiratory failure and even death. Mature Height: 10 Mature Width: Habitat: Woods, scrub and hedges, especially in oak woods, on neutral to calcareous soils[9, 17, 200].
Medicinal Information: The fruit is astringent and laxative[4, 9]. The crushed fruit pulp can be used as a poultice to heal inflammations or small flesh wounds[7]. The fruit is eaten to obviate constipation[240].
The bark, and especially the root bark, is anthelmintic, refrigerant and soporific[218, 240]. An infusion is used in the treatment of intermittent, remittent and bilious fevers[4, 240].
The leaves contain up to 2.4% of an antibacterial substance called 'phloretin'[240]. This inhibits the growth of a number of gram-positive and gram-negative bacteria in as low a concentration as 30 ppm[240].
