Oregano (Origanum Vulgare) as a Mosquito Repellant
Oregano or Kalabo have a beneficial effect on the human health because of its nutritional and its antioxidant content like thymol and an acid called rosmarinic are potent antioxidants that oregano offers. Research shows that “On a per gram fresh weight basis, oregano has demonstrated 42 times more antioxidant activity than apples, 30 times more than potatoes, 12 times more than oranges and 4 times more than blueberries.” All species help move chi stagnation. Although all species share certain properties, there are some differences; Oregano leaves are used as an anti-inflammatory, diuretic and tonic, bronchitis, colic, flatulence, rheumatism antimicrobial and anti-asthma. Meanwhile, mosquitoes are a family of small midge-like flies, the Culicidae. Although a few species are harmless or even useful, most cause a nuisance by sucking blood from vertebrates including humans. Accordingly, some authorities argue that disease-bearing mosquitoes are the most dangerous animals on earth. With increasing reports of the harmful effects on humans like Dengue, there has been a move to repellents which are organic. These are of the kinds that have had traditional household purposes before their being used as mosquito repellents. An insect repellent is a substance applied to skin, clothing, or other surfaces which discourages insects (and arthropods in general) from landing or climbing on that surface. Insect repellents help prevent and control the outbreak of insect-borne diseases such as malaria, Lyme, dengue fever, bubonic plague, and West Nile fever. Pest animals commonly serving as vectors for disease include the insect’s flea, fly, and mosquito; and the arachnid tick. So, in this case, we used candle as an insect repellant to kill mosquitoes that causes dengue Therefore, this study was conducted to know how effective does Oregano (Origanum Vulgare) as a mosquito repellant.

Statement of the Problem
This study aims to determine whether extract from the leaves of Oregano (Origanum Vulgare) can be a good additive for an anti-mosquito repellant candle. 1.What is the effect of mosquito when treated with Oregano candle? 1.1 100% Oregano extract (100ml) (100g candle wax)

1.2 50% Oregano extract (50ml) (100g candle wax)
2.Is there a significant difference between the two samples that is used in treating Mosquito? 2.1 100% Oregano extract (100ml) (100g candle wax)
2.2 50% Oregano extract (50ml) (100g candle wax)

Definition of Terms
Oregano Plant - An aromatic Eurasian plant related to marjoram, leaves are used as a culinary herb. Strongly aromatic erect, spreading plant, with many branches, with fleshy leaves and stems. Leaves are heart-shaped, 4 to 9 cm long, the margins toothed and rounded, with small flowers. In the study, it is an additive ingredient for mosquito repellent.

Mosquito - The mosquitoes are a family of small, midge-like flies: the Culicidae. Although a few species are harmless or even useful to humanity, most are a nuisance because they consume blood from living vertebrates, including humans. In feeding on blood, various species of mosquitoes transmit some of the most harmful human and livestock diseases. Some authorities argue accordingly that mosquitoes are the most dangerous animals on Earth. In the study, it is the sample that will be tested by a Mosquito Repellent Candle with Oregano (Origanum Vulgare).

Significance of the Study
This experiment will be conducted to know more the accurate and faster way of killing mosquitoes that causes dengue. To make an experiment that could really help the middle-class families as well as everybody in avoiding to be sucked by the mosquito carrier of dengue.

Scope and Limitations
This study focused only to the ability of the Oregano (Origanum Vulgare) extract in killing mosquitos. The variables used in this experiment would be found in...
