Zumbani commonly known as Fever tea or lemon bush is the ultimate flu fighter and immune system booster. It is made from crushed dry leaves of the plant known scientifically as Lippia Javanica. 
 
Although the tea can be consumed for recreation and enjoyment, it is commonly used for medicinal purposes in southern Africa. It's commonly used in calming fever in malaria, influenza and measles cases. In other parts of Africa, Lippia javanica herbal tea is consumed for the treatment of respiratory conditions like asthma and bronchitis.
 
High in phenolic compounds, Zumbani tea has anti-inflammatory, bactericidal and antioxidant properties which makes it a strong neutraliser of free radicals in the human body.
