Historical Significance

The therapeutic use of castor seeds can be traced back to ancient Greece, where they were documented by the esteemed herbalist and physician Pedanius Dioscorides in his seminal work, "De Materia Medica." Dioscorides recognized the seeds' multifarious benefits, noting their efficacy as:

• Expectorants: Aiding in the expulsion of mucus from the respiratory tract.

Production Process

Seed Collection

The journey of our superior castor seeds begins with the careful selection of ripe seeds from the Ricinus communis plant. Each seed is meticulously harvested at optimal maturity to ensure maximum potency and quality.

Hull Removal

An essential step in the preparation of castor seeds for oil extraction is the removal of their outer covering, or hull. This hull harbors ricin, a potent toxin, making its removal crucial for safety. Our advanced dehulling processes effectively eliminate this hazardous component while preserving the integrity of the seed.

Pressing for Oil Extraction

The dehulled seeds are then subjected to a pressing process to extract the treasured castor oil. This mechanical method, which does not involve the use of chemicals, ensures that the oil retains its natural purity and therapeutic qualities.
