Mare's milk, as it is also known, is commonly drunk in Central Asia instead of cow's milk.
Researchers from Nazarbayev University believe the drink can help reduce the risk of developing cancer, The Times reports.
Researchers from Nazarbayev University say mare's milk is filled with proteins that are toxic to breast cancer cells and can help regulate blood pressure.
The study suggests horse milk is higher in albumin - a protein easily absorbed by humans - compared to cow's milk.
These proteins can help control blood pressure and have anti-inflammatory effects, researchers say.
They suggested that mare’s milk could therefore be used in treating inflammatory diseases, while it could also reduce the risk of cancer as it has the protein casein, which is toxic to breast cancer cells.
Professor Almagul Kushugulova, leading researcher at Nazarbayev University’s laboratory of human microbiome and longevity, told The Times: 'Mare’s milk has been consumed throughout Kazakhstan and Central Asia since horses were first domesticated and it is one of the most beneficial animal fats.
'Also, due to its rich composition of enzymes, it stimulates the growth of beneficial bacteria and limits to growth of unwanted bacteria in our guts.'
It's also been suggested children who are allergic to cow's milk can drink mare's milk without having a similar reaction.
