Herbs at drying change. Still bolshemu they are exposed to change at storage, little by little losing the medicinal qualities. The majority of plants become poor-quality in some years, but some spoil within a year and become unsuitable to the use.
Our pharmacopoeia demands annual preparation of fresh materials: leaves belladonny, naperstjanki, a henbane, a dope, inflorescences (cones) of hop, tubers akonita, boligolova, rhizomes of a fern, small horns (myceliums) of an ergot and flax seeds. Rather rare example of improvement of qualities at preservation is represented by a bark krushiny which is preferred to two-year safety.
The place of storage and container, or packing are of great importance For preservation of well dried up material. More all it is necessary to be careful of a crude premise and storage in an open kind; absorbing a moisture, the prepared material collapses, changing in colour, and receives a musty smell. As a result of activity of the microorganisms which have got on it, in particular plesnevyh fungi, material damage is accelerated.
The Premise should be dry, well aired, accessible to frequent survey, therefore under a pantry or a warehouse of herbs it is impossible to take away a shed or a cellar. Not heated room at premises can be a good warehouse.
Those from vegetative medicinal materials which contain strongly aromatic essence, should remain away from other materials. All poisonous materials should remain, certainly, in a separate premise at a full guarantee of impossibility of their mixture with others. If in practice there will be special features in packing for storage, about them there will be a speech at the description of separate plants by kinds.
