Perilla Stem Slices

Perilla Stem Slices (Perilla frutescens) are the dried, sliced stems of the perilla plant traditionally used in Traditional Chinese Medicine (TCM) under the name Sū Gěng (苏梗). This aromatic herb is valued for its ability to move qi, open the chest, calm the spirit, and ease constraint, particularly in patterns involving qi stagnation of the chest and middle burner. Its nature is considered acrid and warm, with a gentle, regulating action that restores smooth movement without harsh stimulation.

In TCM, Su Geng enters the Lung and Spleen channels, where it helps regulate qi, relieve chest oppression, ease fullness, and reduce emotional constraint. It is traditionally used for chest tightness, sensation of obstruction in the throat, emotional tension, nausea, and digestive discomfort caused by qi stagnation. Its mild aromatic quality helps harmonize the middle burner and settle restless qi.

Perilla Stem is often chosen over perilla leaf when a gentler, more grounding qi-regulating action is desired. It is commonly included in formulas for mild anxiety, stress-related digestive upset, pregnancy-related nausea, and post-meal fullness, where smooth qi flow is essential for comfort.

Modern research shows that Perilla frutescens stems contain volatile oils, flavonoids, and anti-inflammatory compounds with documented antispasmodic, digestive-regulating, mild anxiolytic, and circulation-supporting effects. These constituents support its traditional role in qi regulation and emotional balance.

Each batch of Perilla Stem Slices (Perilla frutescens) is carefully harvested and sliced to preserve its woody stem structure, subtle aroma, and warming energetic profile. When decocted, it produces a light, aromatic, gently warming infusion traditionally used to move qi, relieve chest and throat constriction, ease digestion, and promote emotional calm.
