Geranium oils, distilled from plants of the Pelargonium species. 

There are several types of geranium oils produced from cultivated forms, varieties, and hybrids of P. graveolens, and other Pelargonium species such as P. odoratissimum Ait.,... 

The worker in the essential oils soon learns that commercial geranium oils are extracted from several species, varieties, and strains of Pelargonium and not from Geranium... 

No changes in the anticoagulant activity (thromboplastin time or partial thromboplastin time) of warfarin was observed in rats orally coadministered single doses of 500 mg/kg of Pelargonium sidoides and 0.05 mg/kg of warfarin or in rats orally administered 500 mg/kg daily for 2 weeks prior to administration of a single dose of warfarin. The authors noted that coumarin-type anticoagulants inhibit the synthesis of vitamin K-dependent coagulation factors via identical mechanisms in rats and humans, and have a similar pattern of metabolism in both species (Koch and Biber 2007). 

Well-known eudesmane derivatives in flavors and fragrances include a- and p-selinene from the oils of Cannabis saliva var. indica (Moraceae), celery (Apium graeveolens, Umbelliferae) and hops (Humulus lupulus, Moraceae), (+)-a- and (+)-P-eudesmol from some oils of eucalyptus (Eucalyplus macarlhuri), (-)-epi-y-eudesmol with its woody odor from the north African oil of geranium (Pelargonium odoralissimum and allied species), and the almost odorless diastereomeric (+)-y-eudesmol from various ethereal oils (+)-p-Costus acid and (+)-p-costol belong to the constituents of the essential oil obtained from the roots of Saussurea...
