Buko juice or coconut juice is a mixture of coconut water, tender coconut meat, and milk. It is a very refreshing and healthy drink, popular in the Philippines. All you need to do is extract the coconut water, scrape the meat, and put them both in a pitcher. Add milk, sugar, and lots of ice cubes. Allow the mixture to melt and then serve. Since the drink is a combination of coconut water, meat, and milk, it can be safely consumed by pregnant women.
