The effectiveness of cogon grass (Imperata cylindrica) as head lice solution Background and Theoretical Framework of the study:
Cogon grass (Imperata cylindrica), family Poaceae, is an invasive, rhizomatous, aggressive perennial grass. Cogon grass (Imperata cylindrical) is one of the most aggressive grasses worldwide and spreads by an extensive rhizome system and has become one of the most serious invasive species and has become a major problem for landowners, land managers and foresters. Cogon grass produces a very aggressive rhizome that has a very sharp and point tip. Pediculosis capitis (also known as head lice infestation, "nits" and cooties) is a human medical condition caused by the colonization of the hair and skin by the parasitic insect Pediculus humanus capitis—the head louse. Typically, only the head or scalp of the host is infested. Head lice feed on human blood (hematophagy), and itching from lice bites is a common symptom of this condition. The head louse (Pediculus humanus capitis) is an obligate ectoparasite of humans. Head lice are wingless insects spending their entire life on human scalp and feeding exclusively on human blood. Humans are the only known hosts of this specific parasite. Head lice are generally spread through direct head-to-head contact with an infested person; transmission by sharing bedding or clothing such as headwear is much less common. Lice (the plural of louse) are a very common problem, especially for kids’ ages 3 years to 12 years (girls more often than boys). Lice aren't dangerous and they don't spread disease, but they are contagious and can just be downright annoying. Their bites may cause a child's scalp to become itchy and inflamed, and persistent scratching may lead to skin irritation and even infection. Each egg is oval-shaped and about 0.8 mm in length. They are bright, transparent, tan to coffee-colored so long as they contain an embryo but appear white after hatching. Typically, a hatching time of six to nine...
