Valeriana officinalis — the sedative nervine whose reputation rests on a constituent that barely survives the bottle.
Valerenic acid is the headline actor: a sesquiterpenoid that binds the β-subunit of the GABA-A receptor as a positive allosteric modulator, potentiating endogenous GABA tone rather than flooding the receptor the way a benzodiazepine does. Add the valepotriates and a small isovaleric-acid contribution, and the action reads as anxiolytic sedation without the next-day cognitive drag.
Clinically it earns its place in sleep-onset insomnia driven by an overactive mind, situational anxiety with somatic tension, and as supportive cover during benzodiazepine tapers. The somatic emphasis matters: Valeriana suits the patient who is physically wound up, not the purely ruminative one.
A prescribing note worth respecting. Valepotriates are unstable and degrade on drying and storage, so extract form and freshness shape the finished tincture more than with most roots. It pairs well with Humulus lupulus for sleep latency, Passiflora incarnata for racing thoughts, and Scutellaria lateriflora for irritable, wired tension. Dose 1:5 at roughly 3-6 mL up to three times daily; flag the paradoxical stimulation a minority of patients report.
