If you garden near old industrial sites, roadways, or in urban soil with unknown history, understanding how plants naturally detoxify heavy metals could shape which species and treatments actually help your beds thrive.
Salicylic acid is a natural chemical that plants make themselves, related to the active ingredient in aspirin. This review pulls together years of research showing that when plants grow in soil polluted with heavy metals like cadmium, lead, or arsenic, salicylic acid helps them cope by triggering internal antioxidant defenses and working alongside other plant hormones to limit damage. Scientists hope to use this knowledge to help crops grow safely in contaminated soils.
Key Findings
Salicylic acid interacts with multiple other plant hormones to coordinate stress responses during heavy metal exposure
SA promotes production of antioxidant compounds and enzymes that neutralize damage caused by heavy metal/metalloid stress
The review synthesizes mechanisms across temperature, salinity, ozone, and heavy metal stresses, positioning SA as a broad-spectrum abiotic stress signal

A common plant hormone called salicylic acid, best known as the compound in willow bark and aspirin's ancestor, helps plants survive contaminated soils by boosting their internal antioxidant defenses against toxic metals like cadmium and lead.

Plant signaling encompasses the molecular and cellular mechanisms by which plants perceive and respond to environmental changes, hormonal signals, and stress conditions. These signaling pathways regulate fundamental biological processes including growth, development, nutrient acquisition, and
