Nothing will seem too apparent about them until some weeks have passed, at which time their vital roles will become more established. One of the first evidences that they are working is when a particular vitamin, mineral, amino acid or enzyme deficiency is resolved and subtle improvement noticed. Herbs come in different forms such as teas, tinctures, tablets, capsules, powders, and poultices. Each form works in a different way for specific health needs. Each form has an advantage of another.
Teas work quickly, but heat destroys some of their vitamin content.
Alcohol-based tinctures draw out essential oils that none of the other forms can do. Tablets and capsules are very convenient to carry with you and take when travelling somewhere. Powders and poultices are best for external applications to draw out purulent matter from suppurations or to reduce inflammation and swelling. In recent times standardized herbs have become the rage of health professionals and consumers alike. The herb industry is now geared towards this form of herbs more than any other.
