Have you heard of using Frankincense for feline lymphoma?

My 10 year old Siamese had targeted radiation @ Univ of FL Sm Animal Hosp for her nasal lymphoma last fall. Repeat cat scans have shown no recurrence. We did only one chemo tx because at the time I thought it had made her sick AND I understood the incidence of metastasis to be 10-15%.
Now,however, her 3 mo follow up showed 2 small masses, one in each lung, so she will need to resume chemo asap.
I’m wondering if Frankincense & Cedarwood might help her.
