Toxicity

• To humans

  Salix koriyanagi, commonly known as the Korean willow, is not typically recognized for being toxic to humans. Most members of the Salix genus, which includes willows, are not harmful if touched or ingested in small quantities by people. However, willows contain salicin, which is a precursor to aspirin, and large amounts could potentially cause adverse effects similar to aspirin overdose. These effects could include stomach pain, nausea, vomiting, and diarrhea. Overdose might also result in more serious effects such as dizziness, tinnitus, and in extreme cases, breathing difficulties and seizures. Nonetheless, usual contact with or incidental consumption of the Korean willow does not pose a significant risk of toxicity to humans.

• To pets

  Salix koriyanagi, commonly known as the Korean willow, is not generally toxic to pets. Willows are known to contain salicin, which is a pain-relieving compound that is metabolized into salicylic acid, a compound similar to aspirin. While this can be toxic in high doses, casual ingestion of leaves or bark is unlikely to harm domestic animals such as dogs or cats. If an animal were to consume large amounts of the plant, symptoms like gastrointestinal upset, including vomiting or diarrhea, could potentially occur. However, such incidents are uncommon, and the Korean willow is not considered a high-risk plant for pet poisoning.
