Lymphoma is a viral induced cancer. The most effective herbs against lymphoma viruses are pau d' arco and andrographis. Although I prefer to also include chaparral as it is also antiviral and potentiates the antiviral effects of the pau d' arco.  Blend all three powders together in equal amounts and capsule the powder. Recommended dose is 3 capsules three times daily. Easiest way to get them down is to oil the outside of the capsule then push them to the back of the throat. It should not take more than one to two months.
