The South African scientists, working with a British company named
Phytopharm, isolated the active ingredient in lida ,
a steroidal glycoside, which they named p57. After getting a patent in
1995, they licensed p57 to Phytopharm. Phytopharm has spent more than $20
million on lida daidaihua research.
