Sedative-hypnotic and anxiolytic activity linked to jujubosides, spinosin, sanjoinine A, GABAergic modulation, reduced excitatory signaling, and serotonergic effects.

Difficulty falling asleep, anxious irritability, frequent dreaming, sweating, and depleted or stress-exhausted patients.

Sedation synergy with hypnotics and alcohol; caution with serotonergic polypharmacy because a serotonin-toxicity case report has been published.

Anxiolytic-like and antidepressant-like actions, with literature describing serotonergic and stress-modulating effects plus sedative activity in preclinical work.

Stress-related insomnia with irritability, grief, emotional burden, and mood-linked sleep disturbance.

Limited direct insomnia trial evidence as a single herb; monitor when combining with antidepressants, anxiolytics, or multiple sedatives because additive CNS effects are plausible.

Commonly cited for neuroprotective, anti-inflammatory, and possible sleep-promoting activity, although direct human pharmacology data for insomnia remain limited.

Chronic fragmented sleep, nonrestorative sleep, mild irritability, and patients who feel run down.

Hepatotoxicity reports exist in the broader Polygonum multiflorum literature, so use caution in liver disease, with hepatotoxic drugs, or when source quality is uncertain.

Mild tranquilizing effects, possible sleep-quality improvement, immune and cytokine signaling effects, and enhancement of inhibitory neurotransmission through GABA_A-related mechanisms in published studies.

Insomnia with palpitations, anxious restlessness, poor appetite, digestive weakness, or a need for gentler calming support.

Usually gentle, but diuretic tendency and product quality matter; it is not the best single-herb choice when a strong immediate hypnotic effect is needed.

Sedative and anti-stress effects, with reported suppression of norepinephrine activity in the locus coeruleus and broader psychotropic activity discussed in herbal psychopharmacology reviews.

Overthinking, rumination, forgetfulness, dream-disturbed sleep, and mentally agitated insomnia.

Can irritate the stomach in some patients; use carefully in significant gastritis or ulcer tendency, and watch for interaction burden in patients taking multiple CNS-active drugs.

Traditional sedative-hypnotic seed used to calm sleep disturbance, with modern insomnia-specific pharmacology less developed than for Suan Zao Ren but consistent clinical pairing in sleep formulas.

Light sleep with palpitations, night sweats, dryness, or constipation tendency.

Oily and moistening, so it may be less suitable in marked phlegm-dampness or very loose stools; use caution with other sedatives because additive effects are possible.

Adaptogenic and anxiolytic-like activity with monoaminergic, stress-axis, and neurotrophic signaling effects; it is often used to support restoration in stress-linked sleep disturbance.

Stress depletion, chronic fatigue, dream-disturbed sleep, spontaneous sweating, and nonrestorative sleep.

Because of its astringent nature, it may be less suitable in unresolved infectious or strongly excess states; also review hepatic metabolism and drug-interaction concerns when the patient is taking multiple pharmaceuticals.
