It is an effective immune stimulant which increases blastogenesis, antibody responses and increased T and B lymphocyte production. In addition to test tubes it was able to reduce the size of tumors in mice with lymphocytic leukemia. It is also an antiviral. The Japanese are investigating this intensely. Interestingly, it is also effective against mycoplasma and mycobacteria as well as many other bacteria.
Mycobacteria are responsible for diseases such as leprosy or tuberculosis.
Mycoplasma are unusual cell-wall deficient organisms implicated in many diseases and thought to be the hidden source of other such as arthritis. This plant also has unique phytochemicals such as flavonoids and terpenes. One such chemical called scopadulcic acid B has been the subject of intense study by drug companies who since the early 90's have been trying to synthesize it because of its anti-tumor properties. It shrinks tumors in vitro and in mice. The herb also has the usual antispasmodic, hypotensive and antiviral properties.
