How is Castor Oil Cultivated? 

The castor plant is known to flourish in a wide range of soils provided they are deep enough and well-drained. The soil should also have a pH nearing 6 and be free of weeds, fertile, and acidic.

In India, the castor beans are cultivated at the beginning of the monsoons somewhere between late May to early June. Alternatively, they can also be cultivated from late September to early October.

Cultivating the beans between these periods helps ensure proper growth considering the wet weather. The harvest is done before November in India. In dry regions, the harvesting is done once the beans are mature enough.

Harvesting is done by breaking the pod spikes. Once this is done, capsules are stripped and if they are not dry at the time of picking, they are dried post spreading out. They are often dried until the point they turn black.

The beans are extracted from the capsules, beaten with sticks. These are then winnowed and further screened. This helps remove the hulls or the outer covering. Threshers are not commonly used for removing the outer covering as the soft seeds could get damaged.

Extraction of Castor Oil

The oil is obtained from those beans that are ripe enough. The oil is extracted through the cold pressing or expeller-based method. The solvent extraction process is also used. It must also be noted that tempering and grinding processes can not be used to extract oil from castor seeds. These processes can be used on soybeans and flax seeds though.

The industrial process involves cleaning the beans first. These are then sent over to machines which will remove the outer covering. An important point to note is that the more thorough this process is, the lighter will be the oil consistency.

The beans are then processed in a cage press and crude oil is extracted. It is then processed through refining and bleaching steps. The oil is either colorless or slightly yellowish. It has a shelf life of 4 years.

Press-cake is also obtained by pressing and the oil remaining in the cake is obtained through a solvent extraction mechanism. It is known as “Number III Oil”. Although it is not pure enough, it does not lend itself to refining.

The Benefits of Castor Oil

Before going to bed, massage the face with castor oil and wash in the morning. This will help to remove the blemishes as castor oil is known to make the skin radiant. Castor oil also reduces stretch marks.

Castor oil can be used as a conditioner as it has hydrating properties. It helps to keep the hair shiny and prevents itching and bald patches that are related to dryness and infections of the scalp. You can apply castor oil directly to the hair and scalp or after shampooing as a conditioner.

Precautions When Using Castor Oil

Castor oil is suitable only for external uses. You should never ingest castor oil and keep it away from children so they do not accidentally consume it. The beans of the plant contain a toxic compound called ricin.

The process of extraction destroys the toxin and removes its properties. However, it can still trigger allergic reactions in some individuals. Research is underway to prevent ricin from entering the oil. As with any substance, castor oil can be both a cure for conditions and a poison. Used judiciously, it can have several health benefits.

The allergic reactions most commonly associated with castor oil include rashes, itching, burning sensation, and redness. In addition, some side effects are dizziness, difficulty in breathing, and swelling of the throat and face.

It is highly recommended to conduct a small skin patch test and leave it for 24 hours before applying the oil in larger quantities. If you observe any redness or itching, it is an indication of an allergic reaction. Discontinue the use of castor oil immediately and consult your medical practitioner.

Pregnant and lactating mothers should consult their doctor before using castor oil, either cosmetically or medicinally.
