The young branches are purple-green, with pith in the center of the cross-section, a fresh fragrance, and a slightly pungent taste. Perilla leaf can disperse exterior cold and has a relatively strong diaphoretic effect. It is used for wind-cold exterior patterns with symptoms such as aversion to cold, fever, and absence of sweating, and is often used together with ginger; if the exterior pattern is accompanied by qi stagnation, it can also be used together with Cyperus rotundus and dried tangerine peel.

At harvest time, collect fallen leaves in the field and burn them in a concentrated manner; in early spring, clear weeds on field ridges, along ditches, and beside roads.</p><p>2. During the occurrence period, spray early with 40% dimethoate emulsion at 2000 times dilution. However, spraying must be stopped half a month before harvest to ensure that no residual toxin remains on the medicinal material.</p><p>(3) Silver-striped noctuid: from July to September, the larvae harm perilla, and the leaves are bitten into holes or notches.
