Is HYDRANGEA MACROPHYLLA LEAF EXTRACT Toxic to Dogs and Cats?

Toxic - Danger

This can be dangerous at any amount. Contact your veterinarian or poison control immediately if your pet is exposed.

Hydrangea macrophylla leaf extract is derived from the leaves of the Hydrangea macrophylla plant, commonly known as bigleaf hydrangea. It is found in various cosmetic and skincare products due to its purported antioxidant and anti-inflammatory properties. However, when it comes to pets, specifically cats and dogs, Hydrangea macrophylla is considered toxic. The plant contains cyanogenic glycosides, which can produce cyanide when ingested. Symptoms of toxicity in pets may include vomiting, diarrhea, lethargy, and in severe cases, respiratory failure and death. Therefore, it is important to keep pets away from hydrangea plants and products containing their extracts.
