Hausen et al., (1987) cited almost 200 cases in which people have shown allergic reactions to Propolis. In some cases of direct contact with Propolis, this may have also been a result of contamination by other bee products such as pollen or bee hairs. However, extracts and products containing Propolis extracts have been shown to cause allergic reactions as well (Hausen, et al., 1987, Hausen and Wollenweber, 1987 and Ko~nlg, 1988) mostly in the form of contact dermatitis. Hashimoto et al., (1988) identified caffeic acid and its derivatives as the major allergenic agents.
Therefore, with all preparations intended for human or animal luse, small quantities should be tried during the first days, slowly increasing to the full dosage (half for children) in order to test for the compatibility of the preparatino or allergic reactions. Equally, termination of medical treatments prescribed by a physician should be gradual, slowly reducing the daily dosage.
Prolonged chewing of large amounts of raw Propolis may lead to nausea and stomach upsets. Donadieu (1979) recommended chewing one gram at a time, three times a day.
