Tinctures are effective methods of obtaining the mother extracts and consequently a very high concentration of active principles of the plants. They can be made both from fresh or dry herbs, but are the fresh ones which are the strongest. Being alcohol the main ingredient its possible to obtain active principles which are unsolvable in water such as the plant’s essential oils. Tinctures are used both internally and externally and do not need to be consumed right away.
Because they are extracted with alcohol they are preserved for several years and do not need to be stored at low temperatures.
As an alternative to tinctures of alcohol there are also vegetable glycerin tinctures, however these are not as potent. In fact alcohol is the only ingredient which is able to extract some plant components such as alkaloids, essential oils, some esterol, terpenes and resins. Also the immersion in alcohol increases the absorbance of the substances. For instance, by dropping some drops under the tongue they reach blood circulation almost instantly.
In order to make a tincture one should use about 100ml alcohol (45-70º) per 10-20g of herbs. Cut all the herbs available in small pieces and let the alcohol drop on them. Next you should seal it and let it sit for 2-5 weeks on a fresh and dark site. The bottle should shaken daily. When enough time has passed just use a filter and strain all the liquid sorting on a dark flask.
