Gut microbiome-supporting herbs contain diverse phytochemicals that function as prebiotics—non-digestible compounds that selectively stimulate growth and activity of beneficial gut bacteria. Beyond classic prebiotic fibers, these botanicals provide polyphenols, oligosaccharides, phytochemicals, and synergistic compounds that modulate microbial composition, enhance microbial metabolism, improve gut barrier integrity, and produce beneficial metabolites like short-chain fatty ac

Overview The lymphatic system is a complex network of vessels, nodes, and organs that plays an indispensable role in maintaining physiological homeostasis. It serves three primary functions: the maintenance of fluid balance by returning interstitial fluid to the bloodstream, the absorption and transport of dietary fats and fat-soluble vitamins from the digestive system, and the facilitation of immune surveillance by trafficking lymphocytes and antigen-presenting cells through

Overview Cognitive function encompasses the mental processes that allow us to perceive, learn, remember, reason, and make decisions. These processes—attention, memory, executive function, language, and visuospatial ability—depend on the integrity of complex neural networks and the health of billions of neurons and glial cells throughout the brain. Cognitive decline, ranging from mild subjective impairment to devastating dementia, represents one of the most significant global

Overview Anxiety is a normal adaptive response to perceived threat, characterized by subjective feelings of apprehension, worry, and fear accompanied by physiological arousal including increased heart rate, rapid breathing, muscle tension, and sweating. When anxiety becomes excessive, persistent, and disproportionate to the actual threat, it constitutes an anxiety disorder—the most common class of mental disorders worldwide. The lifetime prevalence of anxiety disorders approa

Overview Depression is a complex, multifaceted mental disorder characterized by persistent low mood, loss of interest or pleasure (anhedonia), feelings of worthlessness, disturbed sleep or appetite, poor concentration, and in severe cases, suicidal ideation. It represents one of the most significant global health burdens, affecting approximately 300 million people worldwide, with women experiencing depression at twice the rate of men. Depression is among the few illnesses tha

Overview Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage, serving as a critical warning system that mobilizes protective responses. The perception of pain involves a complex, multi-stage pathway beginning at peripheral nociceptors and culminating in cortical processing, with extensive modulation at spinal and supraspinal levels. This pathway comprises five principal stages: transduction (conversion of noxious stimuli in

Overview The adrenal glands are paired endocrine organs situated atop the kidneys, each consisting of two functionally distinct regions: the outer adrenal cortex and the inner adrenal medulla. The adrenal cortex produces mineralocorticoids (primarily aldosterone, regulating sodium and potassium balance and blood pressure), glucocorticoids (primarily cortisol, governing metabolism, immune function, and stress response), and adrenal androgens (precursors to sex hormones). The a

Overview The parathyroid glands are four small endocrine glands embedded in the posterior aspect of the thyroid gland, responsible for the synthesis and secretion of parathyroid hormone (PTH), the principal regulator of calcium and phosphate homeostasis. PTH acts directly on bone and kidneys and indirectly on the gastrointestinal tract (via vitamin D) to increase serum calcium levels. Its secretion is tightly regulated by the calcium-sensing receptor (CaSR) on parathyroid chi

Overview The thyroid gland is a pivotal endocrine organ that regulates metabolism, growth, development, and protein synthesis through the secretion of triiodothyronine (T3) and thyroxine (T4). This regulation is governed by the hypothalamic-pituitary-thyroid (HPT) axis via negative feedback. Thyroid dysfunction manifests primarily as hypothyroidism (insufficient hormone production, often autoimmune) or hyperthyroidism (excess production, as in Graves' disease). This compendiu

Overview The Task Positive Network (TPN), also known as the Central Executive Network, represents a collection of brain regions—including the dorsolateral prefrontal cortex (dlPFC), anterior cingulate cortex (ACC), inferior parietal lobule (IPL), and insula—that activate during goal-directed, externally-oriented tasks requiring attention, working memory, cognitive control, and problem-solving. TPN function is characterized by its anti-correlation with the Default Mode Network
