Collection Of Medicinal Plants

Collection of medicinal raw content of the active ingredients in different parts of plants varies: in some organs are more, in others they may be entirely absent. For example, the essential oil is found only in rhizomes with roots of valerian, and in the grass (aerial parts of herbaceous plants), it is not, in coil, the maximum amount of tannins contained in the roots, the grass in their much smaller. In this regard, for medicinal purposes do not usually collect all the plant, but only that part which contains the largest number of active substances. Is not the same content of active substances and at different times of plant life. It depends the phase of the growing season and even time of day. In the flowering period the maximum amount of biologically active compounds accumulate in aerial organs, and their roots more in the period of the withering away of the aerial parts. In some plants in the midday hours of active substances is much greater than in the morning and evening.

Therefore, the collection of raw materials should be carried out within a certain period, coinciding with the period of greatest activity of plants. But we must remember that collection calendar dates may vary significantly, and depending on weather conditions: in years with early spring and warm dry summers, they come for one or even two or three weeks earlier than in years with a long cool spring and rainy summer. Kidneys are harvested in early spring, at the time of maximum accumulation of these active ingredients.
