Monk's-hood, also known as aconite, is a poisonous plant that is commonly used in traditional medicine because of its analgesic and sedative properties. It is a popular garden plant due to its attractive blue, purple, or white flowers and its ability to resist cold weather. If you are looking for alternatives to monk's-hood, some good options include belladonna, henbane, and deadly nightshade. Though these plants are also known for their toxicity, they have been used medicinally for centuries and are believed to have powerful healing properties. Other options include wolfsbane, devil's helmet, and leopard's bane, which are all members of the aconitum family.
