Only the lower part of his short internodes bears a rosette of leaves.The leaves are ovate or oblong-ovate with blunt tip and slightly crenate margin, the base narrowed into a winged petiole, shortly pubescent.Before flowering, when there is cool, the edges of the leaves are folded inwards and the young leaves at this time is almost rolled into a tube.Flowers (5-13) bright yellow, drooping to one side at the top of the flower arrows in umbellate inflorescence, similar to the curl.Calyx kolokolchatovzdutaya, pyatinadrezannaya.Corolla tubular, with a small limb of the five blades and a long tube.At the base of each petal limb has an orange spot.At the entran

ce to the corolla tube 5 scales.Five stamens, pistil one with top unilocular ovary.The stamens and pistils in different columns flowers are on different levels.Some - the stigma rises above the anthers, as short thread, in others, on the contrary, are highly stamens and pistil low.This phenomenon is called raznostolbchatostyu (geterostiliey) and is the result of adaptation to the cross-pollination of plants.

to blank sheet of primrose plants from the wild collector must have a license, without which the collection is prohibited.

Collect the leaves in the early flowering of plants, tearing down their arms.In this half of the leaves on each plant is left, so as not to damage the flowering and fruiting.The leaves are dried quickly in attics, but better in furnaces or kilns at a temperature of 90-100 °.In the latter case they retain more vitamin C (ascorbic acid).

Previously harvested and roots primrose containing saponins, but now they collect and use discontinued, as there are other saponin plants with expectorant action.

medicinal raw materials.Ready raw material - sheet primrose (Folium Primulae) consists of a solid and partially fractured leaf structure described above.The leaves are wrinkled on both sides, on the edge of the wavy, city chatye or finely toothed.The stalk is usually 1.5 times the length of the plate, which is from 3.5 to 10 cm.

chemical composition.primrose (dry) sheet contains up to 5.9% of vitamin C. The raw material is also valuable because it can be procured in the early spring, when there are no other sources of vitamin C, and especially when the need for it is great.In addition contains up to 2% of saponins, flavonoids and up to 3% carotene mg and others.

Action and use.primrose sheet applied with a lack of vitamin C.
