Hello Surveyor,
Many thanks for the additional information. Yes, we have easy access to Chinese herbs around here and I live near Manila's Chinatown. However, I have not looked into the herbs yet as my dad's oncologist is strongly against herbal supplements during chemotherapy. As a matter of fact, whenever his doctor's other patients bring up the topic she gets upset and threatens them to stop seeing her altogether should they attempt to take the herbs.
Still, I believe in the efficacy of herbal supplements. A handful of our family friends have suggested Zilongjin tablets (http://zilongjin.com/?osID=1) as it has been working well on their loved ones. Strangely enough these chinese pills are only marketed in the Philippines.... But perhaps it is also being sold in other parts of the globe under a different name.
ZILONGJIN tablets
Ingredients:
Radix Astragali, Radix Angelicae Sinensis, Solani Lyrati Herb, and more.
The supplements definitely sound very promising. My mom and aunt's acquaintances swear by it. However, aside from their official website, there is very few information about it on the internet or none at all. This also goes for anti-cancer chinese supplements in general.
Will definitely write more about Zilongjin when I hear more about it.
