Introduction
Rennet is a traditional substance obtained from the stomach of newborn animals, primarily used in medicine and cheese-making. In classical systems of medicine, it is valued for its therapeutic properties, particularly in digestive, cardiac, and reproductive health. It is commonly referred to as “cheese curd” due to its role in coagulating milk.
Source and Preparation
Rennet is typically obtained from the stomach of a newborn animal, such as a calf or kid, immediately after birth. The stomach is removed while it still contains milk, then carefully dried and preserved for medicinal use.
Important considerations in its preparation include:
- The animal should be newborn or only one to two days old
- It must not have consumed grass or solid food
- The stomach contents should primarily consist of milk
Among various sources, camel rennet, particularly from Arabian camels, is traditionally considered the most potent and effective.
Temperament (Mizaj)
In traditional medicine, rennet is regarded as having a warm and dry temperament (second degree).
Medicinal Properties
Rennet possesses several therapeutic actions, including:
- Anti-phlegmatic (reduces excess phlegm)
- Astringent (tightens tissues)
- Cardiotonic (supports heart function)
- Coagulant (helps in clotting and thickening)
- Regulator of bodily secretions
Health Benefits
Digestive and Phlegmatic Disorders
Rennet is particularly useful in conditions involving excess phlegm, such as:

It is often administered with vinegar and honey to enhance its effectiveness.
Regulation of Body Secretions
One of the unique properties of rennet is its balancing effect:
- It thins thick secretions

This dual action helps restore equilibrium in bodily fluids.
