Tetra-carboxy-methyl-naringenin-chalcone (TCM-NC) is a new cosmetic active derived from naringenin, a flavanone naturally occurring in the peel of citrus fruit and tomato skin. The naringenin isomer naringenin-chalcone has been reported to have potent anti-allergic properties. For this reason the effect of TCM-NC was studied in an in vitro assay mimicking the inflammation pathway of rosacea ski...

A history of pet contact and/or apparent clinical sensitivity was obtained in 65 (55%) of 118 unselected asthmatic children. These 65 children were skin tested and their sera examined for specific IgE using the radioallergosorbent test. Those children who had apparent clinical sensitivities had larger skin test reactions and were more likely to have positive specific IgE results than those with...
