Abstract:

Ischemic diseases primarily affect blood-rich parenchymal organs such as the heart, brain, liver, kidneys, and lungs, while also demonstrating considerable incidence in hollow viscera like the gastrointestinal tract. Patchouli alcohol (PA), an active component derived from traditional Chinese medicinal plants, has been demonstrated across multidisciplinary studies to exert remarkable protective efficacy in the prevention and treatment of cardio-cerebrovascular ischemia, gastrointestinal ischemia, and related ischemic pathologies, effectively delaying the progression of ischemic pathological processes. Current research reveals that PA achieves ischemic protection through three synergistic mechanisms: (i) modulation of the inflammatory cascade, (ii) scavenging of oxidative stress products, and (iii) vasodilation of smooth muscle to improve blood perfusion. This multi-target intervention strategy confers unique advantages in organ protection. The present review systematically elucidates the therapeutic effects and molecular mechanisms of PA in multi-organ ischemic injury, not only expanding modern pharmacological understanding of bioactive components from traditional Chinese medicine but also highlighting its developmental potential as a novel therapeutic agent for ischemic diseases. Notably, PA's multi-target regulatory properties provide critical insights for innovative drug design, promising to overcome limitations of single-mechanism drugs and drive paradigm shifts in anti-ischemic treatment strategies.
