is alfalfa toxic
Although it is regarded as a safe herb, Alfalfaâs saponin content also makes fresh alfalfa a risk for colic in horses and may produce nausea or gastritis in some dogs, especially if it is not in the dried form. Alfalfa seeds also contain a toxic amino acid, L-canavanine, so the seeds should not be used. It is also important to note that alfalfa should only be used in its pre-bloom state as otherwise it can trigger an allergic response in animals who have pollen allergies.
