Natural Standard assigns a letter grade for indications based on the quality of available scientific evidence (view Grading Rationale). Letter grades have the following meaning:
- Strong scientific evidence for this use; - Good scientific evidence for this use; - Unclear scientific evidence for this use; - Fair scientific evidence against this use (it may not work); - Strong scientific evidence against this use (it likely does not work).

Antineoplastons are a group of naturally occurring peptide fractions which were observed by Stanislaw Burzynski, MD, PhD in the late 1970s to be absent in the urine of cancer patients. It was hypothesized that these substances may have anti-tumor properties. In the 1980s, Burzynski identified chemical structures for several of these antineoplastons, and developed a process to prepare them synthetically. Antineoplaston A10, identified as 3-phenylacetylamino-2,6-piperidinedione, was the first to be synthesized.  Read the rest of this entry »

Black tea is made from the dried leaves of Camellia sinensis, a perennial evergreen shrub. Black tea has a long history of use, dating back to China approximately 5000 years ago. Green tea, black tea, and oolong tea are all derived from the same plant.

Black tea is a source of caffeine, a methylxanthine which stimulates the central nervous system, relaxes smooth muscle in the airways to the lungs (bronchioles), stimulates the heart, and acts on the kidney as a diuretic (increasing urine). One cup of tea contains approximately 50 milligrams of caffeine, depending on the strength and size of cup (as compared to coffee which contains 65 to 175 milligrams of caffeine per cup). Tea also contains polyphenols (catechins, anthocyanins, phenolic acids), tannin, trace elements, and vitamins.  Read the rest of this entry »
