If she has stage IV cancer she should maybe consider taking a polysaccharide K (PSK) extract bought from a store or online. This is the anti-tumor compound in turkey tail. Eating the mushrooms or even making a tincture with the mushrooms only gets a bit of the desired compound out. If you want to really retard tumor growth (as opposed to people who take it as an immune booster who are healthy) a purer form of the compound would be better. You need a more sophisticated extraction method (salting out with ammonia) from the mycelium to get really high levels of PSK, which is what is available from some supplement companies. She should talk to her physician about this as well as it could have interactions with other medications.
That looks good Camille. They have a furry /velvety top that also distinguishes them from stereum.
