What to do with unwanted gifts?

When I told my Chinese parents that I was pregnant, my mum ran off to buy a whole bunch of expensive Chinese teas, herbal pills and other things to help with postpartum, she also bought herbal pills for my baby. I’m not against traditional Chinese medicine but honestly, I’m not going to use this stuff. Especially not the pills for myself or my baby. I didn’t follow the Chinese confinement rules that she told me to do. (Don’t shower, don’t eat cold things, don’t touch cold water etc) I’m not close to my mum and after having my baby, I’ve realised that my parents have been more harmful than good. The thing is that I know this stuff probably cost a lot of money, and it makes me feel guilty if I throw it away. It’s not like I can return it too. What should I do?
