Energy Impulse Sdn Bhd is a Malaysian based company, which produces and distributes its herbal tea locally under the brand name RainHill. This special tea is made from Cats Whiskers plant (locally know as Misai Kucing; or scientifically known as Orthosiphon Stamineus), which for centuries has traditionally been used for medicinal purposes in the Southeast Asia region. RainHill herbal tea uses the highest quality herb and goes through the electric oven dehydrator process which seals in its flavor. Only 100% of the Cats Whiskers leaves are used in each teabag, resulting in the most pleasant taste and fresh aroma. The tea is light in texture, light golden colour and high in therapeutic values.
