What is the best investigatory project that you can make?

Answer 1

Herbal Mosquito Repellent

A mosquito repellent lotion from the leaves of atis (sweet sop) was invented by the Philippine Council for Health Research and Development (PCHRD). PCHRD is one of the five sectoral councils of the Department of Science and Technology (DOST), according to them, the atis lotion mosquito repellent was created using the extracts of atis leaves mixed with other locally accessible materials. According to PCHRD, the atis lotion is made of 10.125 percent mineral oil, 1.02 percent sodium carboxymethyl cellulose, nine percent propylene glycol, 0.22 percent methyl paraben, 0.135 percent propyl paraben, 70 percent water, and 10 percent plant extract.

Atis leaves, unripe fruit, and the seeds of atis (Anona squamosa) contain vermicidal and insecticidal properties. It is an inexpensive alternative in avoiding mosquito-borne diseases like dengue, malaria, and filariasis.
