The main components are essential oil and rosmarinic acid. The pharmaceutical use as watery or alcoholic extract is due to its sedative, spasmolytic and antiviral effectiveness.  In the framework of the “Demonstration-sprojekt" “Verbesserung der internationa-len Wettbewerbsposition des deutschen Arznei- und Gewürzpflanzenanbaus am Beispiel der züchterischen und anbautech-nologischen Optimierung von Kamille, Bal-drian und Zitronenmelisse" (KAMEL), lem-on balm stands as a example for leafy drugs. This conglomerate of different projects tries to optimise the whole process of generating quality drugs and concerns plant breeding, plant growing, harvesting and drying. In 2010 and 2011 92 accessions of lemon balm from the collec-tions of the federal state institute for agri-culture of Bavaria and the ex situ gene bank of the Leibniz-Institute of Plant Ge-netics and Crop Plant research were tested in field trials. Special attention was given to agronomical qualities like winter hardiness, yield and essential oil content.  On the basis of these trials we could meas-ure the potential of single accessions and evaluate the relation between morphologi-cal properties and qualitative characteris-tics. With the help of molecular markers (AFLP), we were able to generate the first phylogenetic tree of Melissa officinalis, which shows the degree of relation be-tween the accessions and the collections. This information was of considerable im-portance for choosing partners for cross-ing.      16
