Does Chinese medicine interfere with chemotherapy?

Ramo

Hello,

 

My mom has stomach cancer and she is doing chemo every 2 weeks. I bought her some products from a Chinese store to help her with the side effects. There are supposed to be natural. Does anyone know if they could interfere with chemo? 

One is called Naturin2 and is supposed to rejuvenate after chemo. There are some bottles that she is drinking before eating. And she also has some tablets for pain, I don't remember the name, but she said she feels better after taking them.

Thank you
