Everything You Need To Know About Castor Oil

The external use of castor oil can be useful for both aesthetic and medicinal purposes, as it is ideal, for example, to relieve muscle pain.

Castor oil is obtained from the seed of the same name. Sometimes the leaves are also used. In its composition you can find fatty acids, to which their incredible properties are attributed.

This shrub is also known as the infernal fig tree or castor, it is poisonous and belongs to the Euphorbiaceae family . Its oil could have a number of benefits that are good to know.

How do you get the castor bean?

Castor bean, as stated by research published in 2021, has been cultivated and used for centuries, and today it is possible to find it in all areas with a warm climate.

  • It is grown annually and its size varies depending on the climate in which it is found. In warm places it is used to decorate gardens.
  • In a temperate climate it can reach a height between 2.5 and 3 meters, while in a tropical climate it can reach 12 meters.
  • Cold climates can be fatal, since castor bean does not survive frost.

Here we explain the main characteristics and benefits of castor oil.

Within its structure the castor bean presents both sexes in a single plant.


  • Its leaves are large, as they can measure between 10 and 35 cm in diameter approximately. However, with proper care they can reach up to 60 cm.
  • These leaves have alternating colors between purple, red and green.


They are found in groups and can reach a length of between 20 and 50 cm. As we have already indicated, castor bean contains the male and female sex in its broad structure, in two different types of flowers arranged in bouquets or inflorescences.

Below we specify the differences between the two:

  • Female flower: They have a diameter of between 1.5 and 3 cm. They are in the upper part of the inflorescence with an ovary formed by three leaves and a pistil destined to capture pollen.
  • Male flower: It measures between 25 and 30 cm. They are in the lower part of the inflorescence and have a calyx and a pedicel of up to 12 mm.

In some places, castor oil is also known as “castor oil,” which is why some people believe that it comes from the animal. However, this is only the result of a bad translation of the English “castor oil”, which refers to castor oil and not to the animal.
