Laetiporus cincinnatus

In some cases eating the mushroom "causes mild reactions ... for example, 'swollen lips' or in rare cases nausea, vomiting, dizziness and disorientation" to those who are sensitive. This is believed to be due to a number of factors that include allergies to the mushroom's protein or toxins which are only somewhat stable at high temperatures. As such, many field guides request that those who eat Laetiporus exercise caution by only eating fresh, young brackets and begin with small quantities to see how well it sits in their stomach. L. sulphureus has a potent ability to inhibit staph bacteria (Staphylococcus aureus), as well as moderate ability to inhibit the growth of Bacillus subtilis.
