Traditional Use

Primary Actions

  • Moistens the Lung and relieves dry irritative cough - regional sweet-lily material used in the same general sphere as Bai He for dryness, post-illness throat irritation, and mild blood-streaked or sticky sputum.
  • Nourishes Yin and quiets restlessness - often taken as a soup or food-medicine ingredient when recovery, sleep, or emotional calm is the goal rather than forceful clearing or transformation.
  • Supports convalescence and depleted fluids - especially when poor recovery after illness, dryness, and mild fatigue coexist and a gentler edible lily is preferred over harsher medicinals.
  • Acts as a local substitute or culinary analogue to Bai He - preserving much of the same Lung-and-Heart nourishing direction while leaning more obviously toward food use.

Secondary Actions

  • Chuan Bai He usually refers to regional sweet lily materials associated with Lilium davidii and especially the Lanzhou sweet-lily line, so its trade identity is less standardized than pharmacopeial Bai He.
  • Because the bulbs are sweeter and less bitter than core medicinal Bai He, clinicians often view Chuan Bai He as gentler and more food-oriented even when the overall action profile remains Lung/Heart Yin support.

Classic Formulas

  • Bai He Gu Jin Tang (百合固金汤) - when Chuan Bai He is used in place of generic Bai He, the emphasis stays on moistening Lung Yin, easing chronic dry cough, and relieving blood-streaked sputum.
  • Bai He Di Huang Tang (百合地黄汤) - regional cooks and practitioners may use sweeter Chuan Bai He material when treating the restless, post-febrile Bai He Bing sphere through food-like preparation.
  • Bai He Zhi Mu Tang (百合知母汤) - demonstrates the same Yin-restoring, deficiency-heat clearing direction that Chuan Bai He inherits when treated as a local Bai He substitute.
  • Sweet lily soups with Sha Shen, Mai Men Dong, and Chuan Bei Mu - common convalescent pairings that highlight the gentler respiratory use of regional lily bulbs even outside highly formal prescriptions.

Classical References

  • Me & Qi's Bai He identity section notes that Lanzhou lily and other sweet edible lilies are not the main pharmacopoeial medicinal source, which helps explain why Chuan Bai He sits in a gray zone between food ingredient, regional substitute, and medicinal lily bulb.
  • Botanical and horticultural references commonly associate 川百合 with Lilium davidii and related western-China sweet-lily cultivars, distinguishing it from the more bitter medicinal Long Ya Bai He line.
  • This library keeps Chuan Bai He as a separate regional record rather than collapsing it fully into Bai He because the source dataset imported both names and modern trade usage often differentiates them.

Modern Research

Active Compounds

  • Lilium davidii polysaccharides (glucomannan-rich heteropolysaccharides) - dominant sweet-lily macromolecules characterized across bulb extracts
  • O-acetyl glucomannan - a named polysaccharide fraction studied for antioxidant and anti-aging effects
  • Selenylated lily polysaccharides - modified research fractions with stronger immunoregulatory activity in vitro and in vivo
  • Phenolic and flavonoid compounds - supportive antioxidant constituents found in edible lily research
  • Starch and soluble sugars - unusually prominent nutritional components that explain the bulb's sweet food-medicine identity

Studied Effects

  • Lilium davidii var. unicolor polysaccharide studies repeatedly show antioxidant and antibacterial activity, giving modern support to its use as a restorative edible bulb rather than a harsh medicinal (PMID 30986468; PMID 32608519).
  • Chemical characterization work identified major non-starch polysaccharide fractions in the sweet bulbs, helping define Chuan Bai He's food-medicine chemistry (PMID 20221942).
  • Modified polysaccharide research found immunoregulatory activity for selenylated Lilium davidii fractions in vitro and in vivo (PMID 33592405).
  • Root-derived O-acetyl glucomannan prolonged lifespan and improved stress resistance in C. elegans models, adding to the bulb's modern longevity and nutraceutical framing (PMID 32229205).

Safety & Interactions

Contraindications

  • Wind-Cold cough with copious thin sputum
  • Spleen and Stomach deficiency-cold with loose stools or diarrhea
  • Marked phlegm-damp congestion without dryness

Cautions

  • Chuan Bai He is often eaten as a food, but large medicinal amounts are still cool and moistening enough to burden weak digestion
  • Trade identity is less standardized than core Bai He; regional sweet lily cultivars may be sold under the name, so sourcing determines whether the material is truly medicinal or mainly culinary
  • Use caution in pregnancy at medicinal doses because species-level safety data are limited even though culinary use is widespread
  • MSK page not found - drug interaction data not available from Memorial Sloan Kettering integrative medicine database
