Wormwood is probably best known for being the main ingredient in the drink Absinthe, which was popular in France in the nineteenth century. Manet painted in 1876 a painting called `l`Absinthe`. The plant contains a green camphorated volatile oil which gave the drink its distinctive colour. The drink was subsequently banned in France in 1915 because of the damage it caused to the nervous system if consumed in large quantities. This should not, however, stop you from using the herb sensibly, in small quantities and over a short period of time. Wormwood was first introduced to Britain by the Romans during the 500-year occupation. It was brought there and used to rid both the population and the cattle of worms. Wormwood works by triggering an increase in stomach acid and digestive enzyme productions. It also has antimicrobial properties that allow it to inhibit parasites and bacterial growth. Horses will eat this herb readily if they find it in their grazing, despite the fact that it is one of the most bitter herbs available. This is what makes it ideal as a digestive aid and to stimulate appetite. As the name would suggest, it is a powerful worm expellant, especially against roundworm and threadworm. It can be used externally as an insectidal lotion for infestations such as lice, and in cases of mange. DO NOT USE ON PREGNANT MARES AND USE ONLY FOR SHORT PERIODS. DOSAGE: make a brew using 15 grams of cut herb with 3/4 litre of boiling water. INTERNALLY - give 140 ml. per day for a maximum of 3 days (it may be advisisble to mix the brew with a dessertspoon of honey). EXTERNALLY - use the brew as a lotion as required.
