710 MANUAL OF POISONOUS PLANTS 



"seeds" are used for genitourinary troubles. Savory (Satureia hortensis) an 

 annual herb of Europe, sparingly run wild in western United States, is used 

 as a pot herb. The patchouli (Pogostemon Heyneanus) is used by the Arabs 

 to scent mattresses and shawls. Sage (Salvia officinalis) is cultivated as a pot 

 herb and contains pinene, cineol, thujone and borncol. Marjoram (Origanum 

 majorana), a perennial plant native to South of Europe, and cultivated as an 

 aromatic herb, is also an excellent honey plant containing citral. Many species 

 of mints, like the brilliantly colored South American sage (Salvia coccinea, S. 

 splcndens, etc.) and others native to the southern states and the west, are culti- 

 vated for ornamental purposes. The lance leaved sage (S. lanceolata) is a 

 troublesome weed in the West. S. officinalis of Europe, a stimulant and tonic, 

 contains cineol and sahiol C 10 H 18 O, and is commonly used with meat and 

 sausage in German communities. The Japanese potato (Stacliys Sieboldii), is 

 used as the Jerusalem artichoke is. Sweet balm (Melissa officinalis), a pot 

 herb, contains a bitter principle. 



Cymol, C 10 H 14 O, one of the benzol derivatives, occurs in many of the 

 Labiates, especially in Thymus officinalis, Monarda punctata, and Micromeria 

 punctata. Thymol, a benzol derivative, is also found in Origanum floribundum 

 and Monai'da citrlodora.
