All of these mushrooms are available in the U.S. these days, in either dried, fresh or capsule form. You may also wish to explore mind-body techniques for keeping your immune system working for you during chemotherapy. Don't underestimate visualization techniques, meditation and prayer. The use of antioxidant vitamins and minerals during chemotherapy is controversial and needs to be researched. I worry that they may protect cancer cells and so do not recommend their use, but some of my colleagues disagree.
Some chemotherapy agents work by generating free radicals that kill rapidly dividing cancer cells.
Since antioxidants scavenge free radicals, I think they can interfere with the treatment. I suggest discontinuing antioxidants a few days before the start of chemotherapy and staying off them for the duration. You could resume two weeks after you complete your course of treatment.
