Huang Qin (Scutellaria baicalensis)
TCM 'Heat-clearing' root, baicalin and wogonin have antiviral activity in vitro; clinical evidence preliminary.
Why
Huang Qin (Scutellaria baicalensis, Chinese skullcap) is a TCM 'Heat-clearing' root used in formulas for respiratory and inflammatory complaints. Distinct from American skullcap (Scutellaria lateriflora, separate card). Active flavonoids baicalin, baicalein and wogonin have substantial preclinical literature for antimicrobial, anti-inflammatory and antiviral activity. Modern clinical trials are mostly Chinese and small.
How it works
Baicalein and wogonin inhibit lipoxygenase and modulate NF-κB. Antiviral activity against influenza, dengue, and other RNA viruses documented in vitro. CYP3A4 inhibition is real and clinically relevant.
