In addition, the increase in cost of product sales was also due to the boost of the sales quantity and the purchase price of Sanqi which is the main raw material of our main product Xuesaitong.

Gross margin: Our gross revenue for the three months ended March 31, 2012 was approximately $6.7 million in comparison with approximately $5.6 million for the 90 days ended March 31, 2011, a rise of around $1.1 million, or 18.9 percent.
