Eventually pharmaceutical giant Pfizer (makers of Viagra) caught wind of lida
daidaihua and became interested in developing a lida
daidaihua drug. In 1998, Phytopharm sub-licensed the rights to develop p57
to Pfizer for $21 million. Pfizer recently returned the rights to lida
daidaihua to Phytopharm, who is now working with Unilever.
