From insect damaged stems a resin called 'Ammoniacum' is exuded. The dried resinous exudat is also known as //Olegum resin// or //Gummiresina Ammoniacum//. "The best quality product is collected as small, pale yellow solid crystals or tears (Ammoniacum lacrimis); blocks or lumps (up to 600g, Ammoniacum in massis) are inferior... Therapeutic category: Ecpectorant, antispasmodic, counter-irritant... The gum contains 60-70% resin, about 12% gum, 0.1-0.3% volatile oil with linaloolacetate, citronellylacetate, sesquiterpenes..."

"Dorema ammoniacum D.Don (Apiaceae) yields a resin which is collected from the aerial parts, mainly the inflorescences, as evidenced in the region of Yazd. It is produced as a defence against negative impacts of an insect (Cemambicydae) living in symbiosis with the plant. The insect perforates the sprouts, which causes the flow of a resin oxidizing and solidifying in sunlight. The resin is mainly collected for the Indian market. | "Dorema ammoniacum D.Don (Apiaceae) yields a resin which is collected from the aerial parts, mainly the inflorescences, as evidenced in the region of Yazd.
