There is one particular herb that you might want to look into that might be helpful with any blood concerns. It is an Ayurvedic herb called Manjishta (I haven't done a post on it). It is known as a blood purifier and so is Tumeric.
As with most herbs, it is best to use a combination of herbs working synergistically.
Throughout this forum we've done a lot of posts on cancer too. You might want to search those out. There might be some information in those posts too.
