Summary

Grass pollen extract adsorbed on to a suspension of L-tyrosine has been tested over 2 years as a treatment for hay fever. Eight- or nine-dose courses terminating at doses of between 1000 and 10,000 Noon units were equally effective when compared either with a placebo or with a pyridine-extracted alum precipitate.
