Walnut leaves are a valuable medicinal raw material. They make decoctions and infusions, in addition, they are used fresh.
The leaves are harvested during the flowering of the plant – in late May-early June (at this time, the maximum amount of vitamin C accumulates in the leaves of the nut) - by plucking off the lobes (individual leaves) from the central petioles. At this time, they are not yet fully developed and have a specific smell.
The leaves are quickly dried in the sun, spread out in a thin layer on a clean cloth or paper (you can dry them in a well-ventilated room). After drying, the spoiled, black and browned leaves are thrown away.
Store ready-made dried leaves for no more than 2 years.
