The manufacture of the essences is generally done by taking the flower of a plant just as it is about the fall and placing it into pure water in a clear crystal bowl. The bowl is then left in the sunshine for eight hours during which time the 'essence' of the flower infuses into the water. 1 ml of this 'mother solution' is then diluted to 75ml by the addition of pure water and then to 100ml by the addition of fine brandy. The resultant liquor is called a 'stock solution'. From this latter, a dosage of 4 drops three times per day is usual.
Further dilutions increase the strength of the essence.
