Japanese honeysuckle (Lonicera japonica) is a plant that has captured both hearts and minds with its fragrant blooms. But amidst its beauty, a crucial question lingers: is Japanese honeysuckle poisonous? Let’s dive into the details to uncover the truth.
What is Japanese Honeysuckle?
Japanese honeysuckle is a perennial vine native to East Asia. Known for its sweet-smelling flowers, it’s a popular choice in gardens. However, it’s also an invasive species in many regions, potentially disrupting local ecosystems1.
Aesthetic Appeal and Traditional Use
In traditional Chinese medicine, the flowers of Japanese honeysuckle are revered. They’re often used to make a soothing tea believed to have health benefits like clearing heat and detoxifying the body2. But, is this plant as harmless as it seems?
Are the Flowers Poisonous?
Good news first: The flowers of Japanese honeysuckle are generally considered safe. In fact, they’re a staple in Chinese herbal remedies. Dr. Bai Wenwu, a seasoned TCM practitioner, confirms that the flowers, when used appropriately, can aid in alleviating discomforts like fever and sore throat3.
Caution is Key
While the flowers are likely safe, moderation is crucial. Overconsumption can lead to issues like stomach upset, especially in those with weak digestive systems. Always consult a healthcare professional before incorporating honeysuckle into your routine.
Are the Berries (Bark) Poisonous?
Here’s where things get tricky. Most experts agree that the berries and leaves of Japanese honeysuckle are potentially toxic. Both humans and pets should steer clear of these parts4.
Symptoms of Poisoning
Ingesting the berries or leaves can cause symptoms like dizziness, headache, nausea, and even vomiting. In severe cases, it might lead to coma. The good news? The berries are incredibly bitter, making large consumption unlikely.
