In today’s high-pressure, fast-paced environment, many individuals report increasing difficulty concentrating, frequent forgetfulness—such as misplacing items or forgetting recent conversations—and persistent mental fatigue. These symptoms are often accompanied by insomnia, dizziness, and generalized weakness. While commonly dismissed as “stress,” this constellation of signs may indicate neurasthenia—a recognized clinical condition characterized by chronic functional impairment of the central nervous system.
Neurasthenia is a functional neuropsychiatric disorder marked by heightened mental excitability alongside rapid exhaustion, diminished attention span, sleep disturbances, and emotional dysregulation—including anxiety and depressive symptoms. From a Western medical perspective, it reflects dysregulation in neurotransmitter systems and autonomic nervous function. Traditional Chinese Medicine (TCM) classifies it under syndromes such as *bù mèi* (insomnia), *jiàn wàng* (forgetfulness), and *jīng jì* (palpitations), attributing its pathogenesis to prolonged overthinking, depletion of heart and kidney qi and blood, and subsequent failure of the mind (*shén*) to anchor properly in the brain and heart.
Among pharmacologic interventions, Wuling Capsules—a standardized TCM formulation—have demonstrated consistent efficacy in managing memory deficits associated with neurasthenia. The active ingredient is powdered mycelium of *Xylaria nigripes*, a fungus cultivated under controlled conditions and validated for neuroregulatory properties. Clinically, Wuling Capsules are indicated for insomnia, forgetfulness, palpitations, lassitude, and low back or knee soreness—all manifestations of “heart-kidney disharmony” in TCM theory.
Preclinical and clinical studies support its multimodal mechanisms: modulation of GABAergic and monoaminergic neurotransmission; enhancement of synaptic plasticity; neuroprotective effects against oxidative stress and hypoxia; and immunomodulatory activity. Toxicological assessments have confirmed an excellent safety profile, with no evidence of organ toxicity or clinically relevant drug interactions.
A randomized controlled trial involving 180 patients with neurasthenia compared standard treatment with flupentixol-melitracen alone versus combination therapy with flupentixol-melitracen plus Wuling Capsules. After four weeks, the combination group showed significantly greater improvement in core neurasthenic symptoms—including subjective memory complaints—and higher rates of antidepressant response. Sleep architecture and daytime alertness also improved more robustly in the combination arm, underscoring synergistic benefits on both neurovegetative and affective domains.
Pharmacotherapy should be integrated with nonpharmacologic strategies. Evidence-based lifestyle modifications include maintaining consistent sleep-wake cycles, limiting screen exposure before bedtime, and engaging in mindfulness-based stress reduction. Nutritionally, foods traditionally regarded as nourishing to the kidney and heart—such as walnuts, black sesame seeds, and goji berries—may complement therapeutic goals by supporting neuronal resilience and mitochondrial function. Crucially, sustained cognitive recovery requires addressing underlying psychosocial contributors, including work-related stressors and maladaptive thought patterns.
Wuling Capsules represent a well-studied, integrative option for neurasthenia-related cognitive decline—not as a standalone “memory booster,” but as part of a holistic strategy targeting neuroendocrine balance, cerebral perfusion, and emotional regulation. When used appropriately within a comprehensive care plan, it supports the restoration of mental clarity, restorative sleep, and sustained cognitive stamina.
