Known in TCM as Bai Mao Xia Ku Cao (白毛夏枯草), this bitter and sweet, cold herb enters the Lung and Liver. Traditionally, it clears heat and relieves toxicity, most often applied for pharyngitis, bronchitis, and upper respiratory infection. Modern research has identified Neo-clerodane diterpenoids (ajugaciliatins A–J) among its active constituents.

Traditional Use

Primary Actions

  • Clears heat and relieves toxicity … used for tonsillitis, pharyngitis, upper respiratory infections, bronchitis, pneumonia with yellow phlegm, and heat toxicity patterns
  • Cools blood and stops bleeding … used for hemoptysis, epistaxis, hematemesis, and hematuria from heat entering the blood level

Secondary Actions

  • Resolves phlegm and relieves cough … used for productive cough with yellow phlegm and asthmatic wheezing from Lung heat
  • Reduces swelling and dissipates masses … used for furuncles, carbuncles, and breast lumps from heat toxicity accumulation

Modern Research

Active Compounds

  • Neo-clerodane diterpenoids (ajugaciliatins A–J) … series of 10 new diterpenoids unique to A. ciliata; moderate neuroprotective effects against MPP+-induced dopaminergic cell death
  • Ecdysteroids (20-hydroxyecdysone, cyasterone, ajugasterone B, ajugasterone C, ajugalactone) … phytoecdysteroids with anabolic, adaptogenic, anti-inflammatory, and hepatoprotective properties
  • Polyphenols … antioxidant flavonoids and phenolic acids
  • Saponins and alkaloids … additional bioactive secondary metabolites

Studied Effects

  • Neuroprotective neo-clerodane diterpenoids … isolation of 10 new ajugaciliatins (A–J) and 17 known analogues from whole plant; multiple compounds exhibit moderate neuroprotective effects against MPP+-induced neuronal death in dopaminergic SH-SY5Y cells, suggesting potential in Parkinson's disease research (PMID 21682262)
