white resin start to form along the cut, solidifying within a few hours... The resin is collected 4-7 days after the incision, with the help of a forged iron tool formed like a spoon. The already existing cut is reincised, and the newly formed resin is collected one week later. The procedure is repeated a third time, rarely a fourth time. The yield of resin is growing with the number of incisions. In average, every plant gives approximately 20 g per season. One ton of galbanum is thus gained from 50.000 individual plants, and 150.000 incisions... \\ | white resin start to form along the cut, solidifying within a few hours...

- | On storage, an essential oil separates from galbanum. This essential oil was separately investigated in samples from 100% pure galbanum. The essential oil is sometimes added to commercial lots of galbanum to ameliorate” the quality, even though this measure will lead to a shift in phytochemical parameters. Within the oil, an inversion of the percentage of δ-3-carene and ß-pinene relative to the resin is observed, together with an almost complete lack of undecatrienes (0.07%). Undecatrienes are a major constituent of galbanum. In our screening, we found plant populations where the contents of undecatrienes reached up to 4.2 percent... \\ | + | On storage, an essential oil separates from galbanum.
