Bottle Brush or Weeping Willow Insect repellant and spray, deodorant and ointment

Dr Abe V Rotor

Direct crude extract (ground fresh leaves) repels mosquitoes and flies. It also serves as fresh deodorant in the bathroom and kitchen.  

Dilute with tap water at 1:4, filter with ordinary cloth, and spray (atomizer) on garden plants and in dark corners.

Bottle Brush or Weeping Willow (Salix sp)
Another preparation is by dissolving the fresh extract with ethyl alcohol 1:2 ratio, air dry, and add Vaseline or Petroleum Jelly to the powder residue. This also serves as ointment of minor wounds and skin problems.    

The mosquito repellant that is advertised is made of synthetic compounds and there are reports that it is carcinogenic, affecting not only the skin but internal organs as well, since poison can be absorbed by the skin and goes into the blood stream which circulates throughout the body.Researchers from the University of Santo Tomas found out that the volatile oil of the weeping willow, also known as bottle brush (named after the form and shape of the leaves) is an effective mosquito repellant. The oil is extracted by dissolving the ground dried leaves with ethyl alcohol as solvent.
Results of the experiment showed that the extract is effective in repelling house mosquitoes (Culex pipens) with the same efficacy as the advertised commercial product. The result also validates the old practice of using weeping willow to ward mosquitoes by simply rubbing crushed fresh leaves on the skin. (Clemente R, Landan RP Luquinario MI and P Padua, UST 2002)
