Everyone knows the summer solstice solar terms. What about the solstice grass in summer?

Summer solstice grass can be seen in many places except southeast and south China from low altitude to plain slopes, grasslands and roadsides. It is called summer solstice grass, but it does not bloom until summer solstice, but withers around summer solstice, hence the name. It blooms in the plain in early spring and in the mountains in late spring and early summer, which is one of the roadside weeds. Cymbals of Labiatae have sparse flowers, and the flowers grow on white flakes. The petals are two, the upper lip is full, the lower lip is three-lobed, and the flowering period has a strong grass fragrance. Although unremarkable, no one cares about it, it has medicinal value: the whole herb is used as medicine, which has the effect of nourishing blood and regulating menstruation, and treating anemia and dizziness. Take it home, wash the roots, leaves and flowers, and dry in the shade to make tea. Note: areas with serious environmental pollution had better be careful!
