I always recommend checking with the oncologist (or oncology pharmacist) before taking new substances or medications, even if they are considered "natural." Medications, supplements, teas, etc can have interactions with chemotherapy or reduce its effectiveness. Always best to check for your individual case and bring a list of medications and supplements to every appointment.

@duckduck2020, encorafenib in combination with cetuximab for metastatic colorectal cancer with a BRAF V600E mutation was just recently approved by the FDA. I'm glad that your husband has been given the opportunity to get this treatment. @sepdvm might be able to share her experiences with cetuximab.

I can imagine that you're more worried about the obstruction and what that might mean. If you'd like to ask other members about living with an ostomy (the bag), we have a group here:

Is your husband drinking lots of water? How are YOU doing?
