Answer

In April 2014, the FDA approved an SL tablet consisting of 5 calibrated grass pollen extracts (Oralair). It contains Perennial Ryegrass (Lolium perenne), Kentucky bluegrass (Poa pratensis), Timothy grass (Phleum pratense), Orchard grass (Dactylis glomerata), and Sweet Vernal grass (Anthoxanthum odoratum).
