Medicinal use of Rock Rose: This plant is an aromatic, expectorant, stimulant herb that controls bleeding and has antibiotic effects. It is used internally in the treatment of catarrh and diarrhoea and as an emmenagogue. The leaves are harvested in late spring and early summer and can be dried for later use, or the resin extracted from them. The glandular hairs on the leaves yield the oleo-resin 'labdanum', used medicinally and in soaps, perfumery, fumigation etc. This resin is an acceptable substitute for ambergris (which is obtained from the sperm whale) and so is important in perfume manufacture. The resin is collected by dragging a type of rake through the plant, the resin adhering to the teeth of the rake, or by boiling the twigs and skimming off the resin. Edible parts of Rock Rose: The leaves are used as a tea substitute. The oleo-resin obtained from the leaves and stems is used as a commercial food flavouring in baked goods, ice cream, chewing gum etc. Germination of Rock Rose: The seed usually germinates in 1 - 4 weeks at 20C. Prick out the seedlings as soon as they are large enough to handle into individual pots. Grow them on in the greenhouse for their first winter and plant them out the in the following spring or early summer, after the last expected frosts.
