Ajowan Oil (Carum copticum, Bth.). 
Britisu.—India, Egypt. Forrran.—Persia, Afghanistan, &. 
The oil has stimulative and carminative properties and is 
obtained from the fruits. It is rich in Thymol, and as most of 
the Indian exports of Ajowan seeds went to Germany before the 
war an ymol was obtained from Germany that substance has 
become scarce. By the end of 1914 the price of seed had risen 
from 6/6 to 21/6 per lb. The following new sources of Thymol 
have been suggested. Cunila mariana, Monarda punctata, Mosla 
japonica, Ocimum gratissimum, Ocimum viride, Origanum 
floribundum, Origanum hirtum, Satureia Thymbra, Thymus 
vulgaris. See Bulletin of the Imperial Institute, Vol. xu. 
pp. 601-602. In K.B. 1916, p. 88 further information is given. 
Caraway Oil (Carwm Carvi, L.). 
Britisu.—British Isles, India. Forreran.—Holland, Ger- 
many, Russia, &e. 
The oil, obtained from the fruits, has been scarce during the 
_last year or two, and prices have advanced from 6, er lb. in 
January, 1915, to 9/ - per lb. in December, 1915. The cultiva- 
tion of this plant might be increased in the British Isles. 
Ylang-Ylang Oil and Cananga Oil (Cananga odorata, Hk. f. 
& Thoms.). 
Foreicn.~-Luzon, Java, Bourbon and Madagascar. 
Ylang-Ylang Oil is obtained by distillation from the fresh 
flowers of Cananga odorata and Cananga Oil from dried flowers of 
the same tree. Much of the trade seems to have been conducted 
through Germany. As the tree is common in the Malay 
Peninsula the extraction of the oil might be carried on in British 
Colonies. The price of the oil is at present about 10/- per lb.
