The Herb Cabinet 本草
黄芩 huáng qín
Scutellaria baicalensis · Baikal skullcap
“One of my three yellows — this one for the upper burner. Where huang lian cools the gut, huang qin cools the chest: hot coughs, bitter mouths, restless heat.”
— Lao Xinglin
What the tradition says
The pharmacy keeps three great bitter yellows — huang qin, huang lian, and huang bai — famously dividing the body's three burners between them. Huang qin takes the top: hot phlegmy coughs, high fevers with a bitter mouth, damp-heat in the chest and gallbladder[1]. It also cools the blood in hot bleeding patterns, calms heat-type restlessness in pregnancy (a classical "quiet the fetus" herb), and partners chai hu in the shao yang formulas for lingering half-in-half-out illness[1].
What the research says
Baicalein and baicalin, the root's flavones, are laboratory darlings — anti-inflammatory, antioxidant, and cancer-cell studies abound — but human trials are the missing floor of the building: MSKCC's summary is that larger human safety-and-efficacy studies are still needed[2].
Where to be careful
- Liver: acute liver injury has been reported with products containing skullcap compounds[2] — stop and seek care for fatigue, nausea, dark urine, or yellowing.
- Interactions: it may blunt statins, add to bleeding risk with anticoagulants, and shift CYP-metabolized drug levels[2].
- Tradition's own line: too cold for the cold — pale, chilly, loose-boweled patterns[1].
In the pharmacy
The golden root of Scutellaria baicalensis, sliced to show a hollowing amber core. Not the same plant as American skullcap (S. lateriflora) — different species, different uses, chronically confused on supplement labels.

Under the modern lens
Chemists have catalogued some 426 distinct compounds in huáng qín. The ones their papers return to most often:
