Pecah beling or scientific name is Strobilanthes crispus or Saricocalix crispus (Acanthaceae).This plant has a high content of calcium carbonate. The study by Kusumoto and colleagues (1992) states that the water extract of Pecah Beling has a compound or molecule that is able to retarded growth retrovirus; agents in viral infections such as acquired immune deficiency syndrome (AIDS) and is also able to retarded growth of leukemia cells.
From laboratory studies conducted by the Faculty of Medicine and Health Sciences, Universiti Putra Malaysia (UPM), Pecah Beling leaves has a very high content of minerals such as potassium (51%), calcium (24%), sodium (24%), iron (a %) and phosphorus (1%). The leaves also contain vitamins C, B1, B2 is relatively high, and many other materials such as katekin and tannins. The leaves also contain caffeine, but its content is low. All the content shown to contribute to the levels of total antioxidants (total antioxidant activity) is very high when compared with yerbamate (herbal tea) and vitamin E (alpha-tocopherol).
For anticancer research, the praklinikal study was conducted to evaluate the effectiveness of Pecah Beling extracts in vitro (tissue culture) and in vivo (animal studies). For tissue culture studies, extracts of Pecah Beling to act effectively retarded cell growth of colon cancer, liver cancer and breast cancer. This extract is able to induce cancer cells to kill cancer cells is a natural death (apoptosis) without side effects or irritation. In addition, extracts of Pecah Beling is also capable of suppressing cancer-causing genes, thereby reducing the risk and severity of cancer. For animal studies, the water extract of Pecah Beling on the concentration of 2.5% and 5% are able to reduce the severity of liver cancer in rats induced liver cancer.
Fitosterol (from plant sterols) have been successfully separated from the Pecah Beling leaf. This material has proven to be able to retarded growth of cancer cells as mentioned above. This material is also said to be able to lower blood cholesterol levels because fitosterol will compete with cholesterol in the intestine, thus causing cholesterol from food can not be absorbed.
Pecah Beling leaf water extract was tested for its effectiveness as an agent antidiabetis induced diabetes in rats. Pecah Beling leaf extract at concentration of 5% and 7.5% are able to lower blood sugar levels and increase levels of total antioxidants (total antioxidant level) for the blood of rats induced diabetes or diabetes. Extracts had no effect on blood sugar levels in normal rats, but is able to increase the level of total antioxidants (total antioxidant level). Increased levels of total antioxidants (total antioxidant level) in the blood is essential to protect the body from free radicals. Thus, this extract is suitable not only for those who are sick, but also for normal people.
The leaf of Pecah Beling plant has contains many nutrients. It has a high amount of antioxidants as well as able to act as an antioxidant agent, anticancer, and antimicrobial antidiabetes.
