The leaf is the leaf bandotan (Ageratum conyzoides). We often see these plants grow wild in the yards, and sometimes weed farms. The children of ancient times often pick flowers and used as materials to play the market-market. Unexpectedly, it turns out bandotan have extraordinary benefits for health. Here are some benefits of leaf bandotan that we can use.
Mosquito repellent
Based on research by Noer Moehammadi, from Biology Program of Airlangga University, as published in online journal berkalahayati.org (taken 24/8/2017), it turns out bandotan leaf is toxic (toxic) for Aedes aegypti mosquito which is the cause of dengue fever. In his research, leaf extract bandotan was able to kill up to 97% of this deadly mosquito larvae. This is due to the content of flavonoids, alkaloids, and essential oils on the plant, which is important as a toxin.
Mosquito is a serious problem for society, especially if mosquito dengue fever. From cnnindonesia.com (17/06/2016), Indonesia is ranked second of dengue endemic countries of 30 dengue endemic countries. The use of bandotan extract is not only effective, but also safe for us. We can blend leaf bandotan, mix with enough water, then discard the dregs. Liquids and bandotan can we mix to places where there are puddles of air such as ponds, tanks, water tendons, or wells.
Anti Bacterial Compounds
In addition to eradicate mosquitoes, bandotan also has antibacterial properties. Durodola's research from the University of Ibadan, Nigeria, gives results in thieme-connect.com (taken 24/8/2017), mentioning bandotan extract (Ageratum conyzoides) was able to eliminate bacterial activity, especially Staphylococcus aureus.
According to the site alodokter.com (taken 24/8/2017), Staphylococcus aureus is the cause of various types of diseases, such as bacteremia, endocarditis, osteomyelitis, and skin diseases. About 30% of these sites have bacteria inside, let alone the nose.
Staphylococcus aureus is an example of a bacterium whose research has been successfully inhibited by growth of leaf extract of bandotan. Regarding the principle, almost all types of bacteria can be inhibited by the chemical content of this plant. This is the idea of my little time, people, based on experience, using this leaf as a medicine for injury that is quite effective, because it can heal the infection. Bandotan leaf extract can be used also to treat skin diseases such as ulcers, korengan and so on. Instead, use bandotan extract as an external medicine.

We often feel annoyed, if we see our plants broken by pests, is not it? Actually, we can spray it with pesticide, will, there is a risk of pesticides left in our plants. Of course this is dangerous, especially if we consume the plant. Leaf extract bandotan can be a solution, because it can be a natural pesticide without side effects. Quoted from e-journal.biologi.lipi.go.id (2/2002), farmers in West Java, used to use bandotan leaves as a safe pesticide.
It's easy. Take about a handful of bandotan leaves, mix with a glass of water, then btlend it to smooth. For wider use, for example on agricultural land, would require a larger amount. Okay, do not worry, bandotan leaves usually thrive in the bushes. We can spray the liquid into the plant to
