The species are known in California as "hierba santa." The dried leaves 

 are official in the U. S. Pharmacopoeia, and are used in the treatment of 

 asthma, chronic bronchitis, and inflammation of the genito-urinary tract. 

 They contain two aromatic resins and tannic acid. The plants have long 

 been employed in California as a bitter tonic and a stimulant balsamic ex- 

 pectorant, and sometimes as a remedy for rheumatism. The Coahuilla Indians 

 of southern California applied the leaves as poultices to sores upon men 

 and beasts, and bathed sore parts or fatigued limbs with a decoction of the 

 plant.
