Here are my reasons for using aspirin/salicylic acid, copied and pasted from my thread.
"Salicylic acid (SA) is an endogenous growth regulator of phenolic nature and also a signaling molecule, which participates in the regulation of physiological processes in plants such as growth, photosynthesis, and other metabolic processes. Several studies support a major role of SA in modulating the plant response to various abiotic stresses. It is a well-founded fact that SA potentially generates a wide array of metabolic responses in plants and also affects plant-water relations. This molecule also found to be very active in mitigating oxidative stress under adverse environmental conditions."
"Salicylic acid or orthohydroxy benzoic acid is ubiquitously distributed plant growth regulator [
5].
Salicylic acid has positive effects on plant growth and developmental processes [5–7]. Research findings demonstrated its roles in seed germination, glycolysis, flowering, fruit yield [8], ion uptake and transport [9], photosynthetic rate, stomatal conductance (gs), and in transpiration [10]. Salicylic acid can modulate antioxidant defense system thereby decreasing oxidative stress [11]. Photosynthesis, nitrogen metabolism, proline (Pro) metabolism, production of glycinebetaine (GB), and plant-water relations in abiotic stress affected plants were regulated by SA [12–14]. Induction of defense-related genes and stress resistance in biotic stressed plants have also been reported [15]. Moreover, exogenously applied SA showed putative positive effects on stressed plants [16–20]. Salicylic acid induced genes encoding chaperone, heat shock proteins (HSPs), antioxidants, and secondary metabolites of different types. Moreover, SA was involved in mitogen-activated protein kinase (MAPK) regulation, and in the expression [21]. There is no doubt about the vital roles of SA under abiotic stress condition. So, we will review and cover the area regarding the biosynthesis, involvement, and role of salicylic acid on abiotic stress affected plants."

Okay, so awesome. Then I found this.
"Acetylsalicylic acid (C6H4OCOCH3COOH) is the ubiquitous pain reliever known as aspirin."
Salicylic acid (C6H4OHCOOH; it's aspirin's parent compound)...
Salicylic acid is a natural analgesic present in the leaves and bark of certain plants. It is generally unsuitable for internal use, since it is a strong gastric irritant and can cause internal bleeding. In fact, aspirin was invented for this very reason; the acetylated molecule isn't as rough on the digestive tract, although it does hydrolyze to some degree in the stomach."
