Peppertree
Clinical Relevance
IgE-mediated reactions
Pollens from the Peppertree can induce asthma, allergic rhinitis and allergic conjunctivitis
In a study of 71 subjects of both sexes, aged from 14 to 40 years, 31% were found to be sensitized to Peppertree pollen, as measured by skin prick testing. All subjects who tested positive were sensitized to Mango tree pollen (Magnifera indica) as well.
Other reactions
Virtually all parts of this tree, including the trunk, leaves, and fruit, have been used in home medicines from Mexico to South America. The dried and roasted berries are used as a Pepper substitute. The essential oil from the fresh leaves of S. molle has been shown to be efficacious against a range of bacteria.
Cross-Reactivity
An extensive cross-reactivity among the different individual species of the genus, and to a certain degree among members of the family Anarcardiaceae (including Cashew nut, Mango, Pistachio nut, poison ivy and poison sumac), could be expected.
Cross-reactivity has been demonstrated between Mango tree pollen and Peppertree pollen.
