I've used the site for years. I'm a patient at MSKCC, but anyone can use it. The one on the internet has amazing depth of information. You can drill down and find every ncbi peer reviewed medical article if you want, or can get just a short summary of effects. The site always addresses how the herb relates to cancer, but also all other med conditions. I just downloaded the app for my phone yesterday (also Free). mmmmIm not sure it is as in depth as the site online you found. Example of how useful it is-----My daughter.-in-law and I were together and she was drinking an herbal tea Ashwatanga (sp?) and offered me some, so I looked it up first on the MSKCC site and it said do not combine with anesthetics---I was just coming out of ( a couple hours later) general anesthesia from my SuperD Navigation Bronchoscopy. Thank goodness for that warning. . In addition. she was then having problems with her pregnancy, and lo behold the site said that tea is known to cause spontaneous abortion. I was bummed after reading all the good reviews on Clear Lungs that I couldnt take it because I had ER/PR tumor-- but better to know. MSKCC actually also has a Chinese med pharmacy at one of their campuses.
