What is known about elderberry cyanidin anthocyanins and neuraminidase, the limits of pharmacokinetic evidence, and why small positive trials coexist with a negative RCT in PCR-confirmed influenza. Raw-material safety and the absence of a universal dose are considered separately.
How Scutellaria baicalensis flavones undergo intestinal metabolism and affect GABA_A, microglia, and lipid oxidation. Molecular pathways, formulas, limits of evidence on sleep and neuroprotection, interactions, and safety.
From root composition and β2/β3-dependent GABA_A modulation to polysomnography: what is known about valerian, deep sleep, adenosine, and 5-HT5A. Clinical reviews, the glymphatic hypothesis, extract standardization, dosing, and safety—with mechanisms distinguished from outcomes in humans.
