Patchouli. ( Pogostemon spp .). — Patchouli is an 
herbaceous plant, about 2 to 3 ft. high, 
cultivated for the essential oil contained in the 
leaves. The plant is propagated by stem cuttings 
planted in carefully shaded nursery beds ; when 
rooted, these are transplanted in the open at dis- 
tances of 2 to 2l/ 2 ft. apart. The first crop of leaves 
may be made about 6 months after planting out in 
the field, and subsequent pickings may be made 
twice a year. It is customary to replant about every 
two years. 
The leaves, after cutting, must be dried in the shade, 
care being taken to ensure that they do not become 
mouldy during the process. When dried, they may 
be either packed in bales for export, or steam

between 2 and 4 per cent, of oil, which is used 
entirely as a perfume. 
The present price (Sept. 1923) of the oil is about
