-"Myrrh, a commercially used resin, is mostly from C.molmol, growing wild in Somalia, Jemen and Arabia. It is mainly used in toothpastes and tinctures for treatment of gingivitis. Myrrh is composed of the essential oil (2-10%), the ethanol soluble resin (25-40%) and the watersoluble gum (30-60%). The watersoluble gum fraction of myrrh has been found to comprise of a mixture of proteoglycans (with dominating amounts of uronic acid polymers)."

The mixture of furanodiene-6-one and methoxyfuranoguaia-9-ene-8-one showed antibacterial and antifungal activity against standard pathogenic strains of Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans, with minimum inhibitory concentrations ranging from 0.18 to 2.8 μg/ml. These compounds also had local anaesthetic activity, blocking the inward sodium current of excitable mammalian membranes. \\

 To prepare pharmaceutical formulations of mouthwashes, containing extracted Yemeni myrrh as a single active constituent, different solvents were used to prepare myrrh extract. An hydroalcohol extract of myrrh with ethanol: phosphate buffer pH 7 (85:15) showed the best antimicrobial activity against Staphylococcus aureus. The selected myrrh mouthwash formulations revealed remarkable antimicrobial activity against Staph. aureus and Strep. mutans, greater than all other tested products with chlorhexidine gluconate or benzydamine HCl. \\ To prepare pharmaceutical formulations of mouthwashes, containing extracted Yemeni myrrh as a single active constituent, different solvents were used to prepare myrrh extract.
