Full Answer

Aspirin contains salicylic acid, which is produced by plants in small amounts as a response to diseases. However, not all plants produce enough of this acid to overcome diseases or infections. When these plants receive water that has been treated with aspirin, their immune systems are boosted by the additional salicylic acid.

Aspirin, when applied to plants as seeds, can also boost germination. The salicylic acid found in aspirin prompts the seeds to engage their defenses. This preemptively protects the seeds from outside threats, such as fungi, bacteria and infections.

If a recently cut plant is placed in a container with aspirin water, it does not wilt as quickly. This is because a plant begins producing a substance to fight off bugs as soon as it detects a cut. This substance is also responsible for the plant's premature wilting. Aspirin-enriched water prevents this substance from forming, and helps the plant appear healthier for a longer period of time.
