Warms and supplements the Kidney while securing essence - Tong Ji Li is a regional name for the Sha Yuan Zi seed and is used for leakage, reproductive weakness, and deficient lower-burner instability.
Benefits the eyes through Liver-Kidney support - its traditional vision use fits deficiency blur rather than red inflamed excess-eye patterns.
Supports fertility and constitutional resilience - it appears in tonic strategies for chronic weakness where reproductive function and essence have been depleted.
Secondary Actions
Tong Ji Li is best understood as a regional or trade synonym rather than as a different botanical medicine from Sha Yuan Zi.
Because it is gentle and seed-based, it often participates in longer restorative formulas rather than acute symptom formulas.
Classic Formulas
Kidney-securing combinations use Tong Ji Li with Tu Si Zi, Fu Pen Zi, or Qian Shi for nocturnal emission and urinary leakage.
Reproductive-tonic formulas may pair it with Du Zhong and Gou Ji when infertility and low-back weakness coexist.
Eye-support deficiency formulas combine it with Gou Qi Zi and other Liver-Kidney nourishers rather than with strong heat-clearing eye herbs.
Classical References
Traditional Chinese trade literature treats Tong Ji Li as an alternate name for the seed more commonly listed as Sha Yuan Zi or Sha Yuan Ji Li.
Its actions remain those of a sweet warm Liver-Kidney tonic that secures essence and improves vision in deficiency patterns.
Regional naming should not be mistaken for a separate herb with a different core therapeutic profile.
Modern Research
Active Compounds
Complanatoside-type flavonoid glycosides - major quality markers across commercial seed samples
Phenolics and antioxidant seed compounds - likely contributors to tissue-protective and metabolic findings
Saponin-like constituents - part of the broader tonic pharmacology profile
Minor lipid and sterol fractions - supportive nutritional components of the seed
Studied Effects
Modern quality-control work on Astragali Complanati Semen identified key bioactive flavonoid glycosides relevant to commercial standardization of Tong Ji Li or Sha Yuan Zi products (PMID 33081333).
Astragali Complanati Semen demonstrated a hypocholesterolemic effect in experimental metabolomics research, showing that current pharmacology extends beyond the herb's classical leakage indications (PMID 28753987).
The seed enhanced bone formation in osteoporotic rats, offering a modern experimental complement to its traditional low-back and deficiency-support role (PMID 23782721).
Preclinical antihypertensive activity has also been reported from total flavonoid fractions of Astragalus complanatus (PMID 16201455).
