Reality show fans watched Tamera Mowry-Housley, who had just given birth, coax her twin sister Tia Mowry-Hardrict into tasting her placenta.

The identical sisters, who rose to fame in 1990s show Sister Sister, filmed the episode for the season finale of their US Style network reality show Tia & Tamera.

Although Tia almost backed out, Tamera, who had recently given birth to a baby boy she called Aden, mixed the planenta with a little brandy, which Tia then drank.

"Tasting Tamera's encapsulated placenta was very interesting," Tia wrote on her blog.

"If you think about it too much, you're not going to like it, because all you're going to think about is that you're consuming placenta. But I was surprised that it tasted pretty good mixed with a little bit of alcohol.

"It was definitely Tamera paying me back for making her taste my breast milk. I tasted my own breast milk and I still think my breast milk was sweeter than Tamera's placenta."

One viewer wrote: "Uck! What's next - eating her excrement?

Another said: "I'm a twin and I would never would never do this. It's not a twin thing ... trust me. Yuck! I'm utterly disgusted."

Eating placenta is popular in some cultures. Not only is it said to be rich in nutrients but also helps the mother recover, according to some beliefs.

Helps with milk supply

Prevents Post-Natal depression

Some doctors believe that eating the placenta is a natural way to ward off postpartum depression and other health problems that are associated
