With one or two exceptions (detection of sesame oil and perhaps also of cotton-seed oil) all colour reactions are entirely useless.
On the continent of Europe the largest oil-trading centres are on the Mediterranean (Marseilles and Triest), which are geographically more favourably placed than England for the production of such edible oils (in addition to the home-grown olive oil) as arachis oil, sesame oil and coco-nut oil.
Mix together 1tsp each of olive oil, sesame oil and lemon or lime juice and ½ tsp coriander seeds.
Give yourself a full body massage with warm sesame oil at least once a week.
Pure Sesame Oil can be used to nourish the skin or massage the body for a smooth, silky soft skin texture.
