yucks drink snake blood!!!

Saw this event at Johore Bahru a couple of days ago....Thought it only happens in discovery travel!

There was this guy selling chinese medication and ointments. There were also 3 cages of snakes.
Watched him took one out of the cage - it's a cobra. His female assistant took out a small sharp blade and then slid open the snake right at the centre downwards and took out the blood vessel with her bare hand and drained out the blood into a cup, the snake was still alive! After which she separated the amount into two 50ml cups mixed with some chinese liquor I think. And then took out a small black thing from below the snake - ?gall bladder ?liver ?testes??? and then rinse it and
split it into two and added them to the 2 cups.

Guess who drink these???? Two young boys (most probably) less than 20 years old!! Don't know why they need it, they look normal and healthy. Cost - RM140 for them
