Herbal medicine (also herbalism) is the study of pharmacognosy and the use of medicinal plants. Plants have been the basis for medical treatments through much of human history, and such traditional medicine is still widely practiced today. Modern medicine makes use of many plant-derived compounds as the basis for evidence-based pharmaceutical drugs. Although herbalism may apply modern standards of effectiveness testing to herbs and medicines derived from natural sources, few high-quality clinical trials and standards for purity or dosage exist. The scope of herbal medicine is sometimes extended to include fungal and bee products, as well as minerals, shells and certain animal parts. The use of herbal remedies is more prevalent in patients with chronic diseases such as cancer, diabetes, asthma and end-stage kidney disease. Multiple factors such as gender, age, ethnicity, education and social class are also shown to have association with prevalence of herbal remedies use. Herbal teas, or tisanes, are the resultant liquid of extracting herbs into water, though they are made in a few different ways. Infusions are hot water extracts of herbs, such as chamomile or mint, through steeping. Decoctions are the long-term boiled extracts, usually of harder substances like roots or bark. Maceration is the cold infusion of plants with high mucilage-content, such as sage or thyme. To make macerates, plants are chopped and added to cold water. They are then left to stand for 7 to 12 hours (depending on herb used). For most macerates, 10 hours is used
Tinctures are alcoholic extracts of herbs, which are generally stronger than herbal teas.Tinctures are usually obtained by combining 100% pure ethanol (or a mixture of 100% ethanol with water) with the herb. A completed tincture has an ethanol percentage of at least 25% (sometimes up to 90%). Non-alcoholic tinctures can be made with glycerin but it is believed to be less absorbed by the body than alcohol based tinctures and has a shorter shelf life. Herbal wine and elixirs are alcoholic extract of herbs, usually with an ethanol percentage of 12–38%. Extracts include liquid extracts, dry extracts, and nebulisates. Liquid extracts are liquids with a lower ethanol percentage than tinctures. They are usually made by vacuum distilling tinctures. Dry extracts are extracts of plant material that are evaporated into a dry mass. They can then be further refined to a capsule or tablet
in the academy we will focus on how to use fruits,leaves,roots,barks in the treatments and managements of diseases. The aim is to be able to train students how to make food supplements that are vital for the maintenance of bodily function and the treatments of diseases. We achieve this by first introducing the students to the different fruits and vegatables that are vital for the supplements preparation.Next we introduce diseases or disorders that can be treated by these supplements,finally we talk about dosage,administration and preservations. the courses are divided into three namely: 1.Beginners supplement preparation(BSP 100) 2.Intermediate supplement preparation(ISP200) 3.Advanced supplement preparation(ASP300)
