Known in TCM as Chao Su Zi (炒苏子), this acrid, warm herb enters the Large Intestine and Lung. Traditionally, it directs rebellious Lung Qi downward and stops cough and wheezing ... Chao Su Zi is used when phlegm, cold, or deficient descent causes noisy breathing, cough, and chest fullness, most often applied for cough, wheezing, and asthma. Modern research has identified Alpha-linolenic among its active constituents.

Traditional Use

Primary Actions

  • Directs rebellious Lung Qi downward and stops cough and wheezing ... Chao Su Zi is used when phlegm, cold, or deficient descent causes noisy breathing, cough, and chest fullness.
  • Transforms phlegm and eases chest constraint ... it is especially suited to cough or asthma patterns where abundant seeds and oily warmth help the Qi descend.
  • Moistens the intestines and unblocks the bowels ... like raw Su Zi, the stir-fried form helps constipation when dryness or weak downward movement coexists with Lung Qi rebellion.

Secondary Actions

  • The stir-fried form is considered slightly more moderate and better directed toward descending and dispensing use than raw seed.
  • This page should stay distinct from the still-stub raw Su Zi sibling ... the preparation note matters because roasting changes both appearance and clinical handling.

Classic Formulas

  • Su Zi Jiang Qi Tang ... classic formula for wheezing, copious phlegm, and rebellious Lung Qi with lower-body weakness.
  • Ding Chuan Tang modification logic ... roasted Su Zi is often chosen when wheezing and downward-directing seed herbs are needed.
  • Run Chang Tang style logic ... oily seed medicinals are used when constipation accompanies deficient fluid movement.

Classical References

  • Traditional materia medica describes Su Zi as warm and descending, especially for cough, wheeze, and constipation from impaired Lung and Large Intestine movement.
  • Stir-frying is a common dispensing preparation that moderates raw seed moisture and brings out a warmer toasted seed character.

Modern Research

Active Compounds

  • Alpha-linolenic acid and other unsaturated fatty acids ... dominant seed-oil constituents
  • Rosmarinic acid and related phenolics ... broader Perilla bioactive compounds
  • Flavonoids and seed proteins ... additional fractions discussed in pharmacologic reviews

Studied Effects

  • A 2017 review summarized the phytochemistry and pharmacology of Perilla frutescens and affirmed that the leaves, stems, and seeds all have documented medicinal use in Chinese medicine (PMID 27890564).
  • Perilla seed oil supplementation reduced leukotriene generation in patients with asthma associated with lipometabolic disturbance, supporting the seed's traditional relevance to wheezing and airway inflammation patterns (PMID 10878492).
  • A 2024 review of perilla seed oil summarized antioxidant, anti-inflammatory, lipid-regulating, neuroprotective, and immunomodulatory findings, offering broader modern support for the medicinal value of the seed itself (PMID 39594031).

Safety & Interactions

Contraindications

  • Loose stool from marked deficiency without dryness or Qi rebellion

Cautions

  • Because the seed is oily and descending, very large use can loosen the bowels in sensitive patients.
  • Perilla seed evidence often comes from seed oil or whole-plant studies, so modern findings are broader than the exact stir-fried dispensing form.
