🌿 What is Castor Seeds (Ricinus communis)?
Castor Seeds are the seeds of the Castor plant (Ricinus communis), commonly known as Amanakku Vithai in Tamil. The plant has been widely used in traditional Siddha and Ayurvedic medicine for centuries. While the raw seeds are toxic and should never be consumed directly, they are highly valued for producing Castor Oil through specialized processing methods. Castor Oil has traditionally been used to support skin care, hair care, digestive wellness, joint comfort, and overall well-being. The seeds are rich in naturally occurring fatty acids, proteins, antioxidants, and beneficial plant compounds that contribute to their traditional importance.
Note: Raw Castor Seeds contain ricin, a highly toxic natural protein. They should only be used after proper industrial or medicinal processing by qualified manufacturers and should never be eaten raw.
