3-Methylthiopropylamine and (R)-3-methylsulphinylpropylamine have been isolated from Iberis amara.

„In pharmacological studies both in vitro (e.g., in guinea pig ileum) and in vivo (e.g., in Wistar rats) the fresh plant extract of Iberis amara (IF) exhibited a tonicising effect on the smooth muscles of the stomach and small intestine. In the rat IF produced a dose-dependent antiulcerogenic effect (indomethacin-induced ulcer) comparable to that of cimetidine (reference substance). The stomach acid release and the leucotriene-concentration, increased by indomethacin, were reduced by IF, whereas the prostaglandin E2 content, reduced by indomethacin, was increased. In patients with irritable bowel syndrome as a subtypological symptom associated with diarrhea and in patients with alternating diarrhea and obstipation, clear differences were found between drug and placebo in a multicenter, prospective, double-blind, randomized parallel group comparison.“
