Aloe Vera Gel

Introduction

Aloe Vera Gel is a clear, thick, and naturally active substance obtained from the inner part of the leaves of the succulent plant Aloe barbadensis Miller. This plant belongs to the Asphodelaceae family (previously classified under Liliaceae/Xanthorrhoeaceae). It is believed to have originated in Africa and the Arabian region, but today it is widely cultivated in India and many tropical and semi-arid regions around the world.

The thick, fleshy, and spiny leaves of Aloe Vera contain nearly 99% water along with a wide range of valuable bioactive compounds. For thousands of years, Aloe Vera has been used in Egyptian, Greek, Chinese, and Ayurvedic traditions for skin care, hair care, and general wellness. In modern times, Aloe Vera Gel has become an important ingredient in the cosmetic, pharmaceutical, nutraceutical, and food industries.
