A similar result was obtained by Kinghorn & Evans (1975a) with the latex using a mouse ear irritancy assay.
In a comparison of different tillage regimes in winter cereals, common mouse-ear was favored by reduced cultivations.
Look out for betony, wild strawberry, germander speedwell, eyebright, wild thyme, salad burnet, mouse-ear hawkweed and common bird's-foot-trefoil.
