If you're into Korean skincare, also known as K-beauty, you're likely familiar with Centella Asiatica. Centella Asiatica is a plant extract that goes by several names including Brahmi, Asiatic pennywort, tiger grass, and Gotu Kola.

It's reputed as an effective ingredient for keeping skin hydrated and healthy.

Castor oil is derived from the seeds, also known as beans, of the Ricinus communis plant, which is indigenous to East Africa. Interestingly, these beans contain a poisonous substance called ricin, which is highly toxic.

Despite certain parts of the plant being toxic, castor oil has been utilized for medicinal purpose.
