The truth behind 'tiger *****'
Over the past two weeks, Sheen has been speaking passionately about his love of tiger *****.
But unsurprisingly the ***** isn't actually from the veins of an endangered species, it's actually mangosteen juice.
The red liquid has been sold by Utah-based company Xango since 2002.
The juice is made from mangosteens - a fruit which originates in South East Asia.
The mangosteen fruit is rich in xanthones - which promote healthy bodily function - and includes five grams of fibre.
Friends of Sheen claims he drinks a bottle every day.
