4. Hair Growth Stimulation: Castor oil can also be used to improve hair growth and strengthen hair structure. Massaging it into the scalp can help increase blood flow to the hair follicles and stimulate hair growth.

Pharmacodynamics

1. Laxative action: Castor oil is widely used as a laxative due to its ability to stimulate intestinal peristalsis and increase the volume and frequency of stools. This is due to the oil's content of ricinic acid, which is the active ingredient and has an irritating effect on the intestines.

Pharmacokinetics

The pharmacokinetics of castor oil has not been the subject of extensive research because castor oil is generally used as a natural remedy rather than as a traditional drug. However, it is known that castor oil can be slowly absorbed through the skin and mucous membranes and has a weak systemic action.

After ingestion, castor oil can form an emulsion in the intestine, which helps its elimination from the body. It may also increase intestinal peristalsis and lead to accelerated digestion and bowel excretion.

Dosing and administration

Basic recommendations for the use of castor oil for different purposes:

Like a laxative

• For adults: The standard dose of castor oil as a laxative for adults is 15 to 60 ml (1 to 4 tablespoons). The oil should be taken on an empty stomach in the morning for fastest action.
• For children: The dosage for children should be much lower and is determined by a doctor. It is not recommended to use castor oil to treat constipation in children without consulting a pediatrician.

For skin care

• Castor oil can be applied directly to the skin to moisturize or treat dry, inflamed areas. The oil should be applied in a thin layer, rubbing lightly until it is completely absorbed.
• To treat acne, castor oil can be applied topically to problem areas before bedtime.

For hair and eyelash care

• To improve hair health, the oil can be applied to the scalp and hair a few hours before washing or left overnight under a hair cap.
• For eyelash and eyebrow growth, apply a small amount of oil to clean lashes or eyebrows before bedtime using a clean brush.

To relieve joint pain

• Castor oil can be used as a compress on painful joints. Apply the oil on a cloth, apply it to the painful place, cover with plastic and heat with a heating pad for 30-60 minutes.
