AB  - Hailstorms cause severe mechanical damage to crops, yet their long-term legacy effects on the physiology of perennial medicinal herbs remain poorly understood. This study examined \textit{Bletilla striata} plants damaged by a severe hailstorm on April 2, 2026. On day 37 post-damage, coinciding with new pseudobulb formation, 44 electrophysiological parameters were measured in leaves of damaged plants ($n = 8$) and undamaged controls ($n = 8$) and compared using Welch's $t$-test. Damaged leaves showed a persistent ``low-resistance, high-capacitance'' pattern: inherent physiological resistance decreased to 25.0% of the control value, whereas inherent capacitance increased 5.6-fold (both $P < 0.001$). Water and nutrient parameters displayed a consistent ``low-efficiency, high-speed'' decoupling, with intracellular water-holding capacity and water and nutrient transport capacities increasing 7- to 22-fold ($P < 0.001$), while the corresponding use efficiencies declined by 61%-95% ($P < 0.01$). Resistance-related metabolic energy increased by 75.7% ($P < 0.05$), whereas capacitive reactance-related metabolic energy decreased by 43.3% ($P < 0.01$), indicating a shift toward energy dissipation. Thus, the leaves had not recovered within 37 days. We therefore propose a testable ``maladaptive stress homeostasis'' hypothesis, in which high-flux transmembrane transport is maintained at the expense of resource-use efficiency and ordered energy storage. Findings are based on Welch's $t$-tests across 44 parameters without multiple-comparison correction, which should be considered when interpreting the reported significance levels. Multi-time-point and mechanistic studies are needed to determine whether this state is stable, slowly recovering, or progressive.
