Plant-based repellents have been used for generations in traditional practice as a personal protection measure against host-seeking insect. Recently, commercial repellent products containing plant-based ingredients have gained increasing popularity among consumers, as these are commonly perceived as "safe" in comparison to long-established synthetic repellents. There is a need for further standardized studies in order to better evaluate repellent compounds and develop new products that offer high repellency as well as good consumer safety. How often have we tried to enjoy the great outdoors or a restful night sleep only to be bothered by what seems like an army of insects attacking us? What is it that attracts insects to humans? Are some individuals more attractive to insects than other individuals? Since insects are vectors for many debilitating human diseases, understanding insect attraction to humans is very important. Study has shown that insects associate with humans at multiple stages in their life cycle. The mechanism of this attraction, i.e. CO2, sweat, ABO blood type, chemicals, body temperature, body humidity. For example, scabies mite, Sarcoptes scabies, which can cause intense skin irritation, has been found to be attracted by host odor, body temperature. CO2 plays a significant role in attraction for numerous insects especially mosquitoes. Other examples of insect attraction to humans include: kissing bugs and sandflies. Study has also shown that the common natural plant like Fennel, Neem, Basil, Coriander are having excellent insect repellent activity with medicinal significance.Keywords

Weeds are unwanted and undesirable plants which interfere with the utilization of land and water resources and thus adversely affect human welfare. They can also be referred to as plants out of place. In crop lands and forests, weeds compete with beneficial and desired vegetation, reducing the yield and quality of produce. But it is also true that while all unwanted plant are weeds, all weeds are not unwanted plants.. Weeds are not unwanted plants for practitioners of Ayurvedic and other traditional systems of healing. For them, weeds are potenital sources of valuable life-saving drugs. In additional, allelopathic and industrial uses of common weeds have been reported. With the help of information available in ancient and modern literature, farmers can utilize these so-called unwanted plants (i.e. weeds) to generate additional income. The present paper is a review article on the weeds of Chhatisgarh and India. Here medicinal significance of 20 weeds of Chhattisgarh and 10 weeds found in other parts of Chhattisgarh has been discussed. These weeds like Boerhavia diffusa, Achyranthus aspera having the medicinal significance can be used for the treatment of many diseases, and also can act as source of income for farmers.Keywords

Application indigenous natural products has been alternative way to replace synthetic medicine Gloriosa superba is a well known ethnomedicinal plant which is used in Ayurveda. Photochemical studies of G. superba shows presence of colchicin, b-siltosterol, long chain fatty acids, b and glumiccolchicines, 2-hydroxy-6-methoxy benzoic, luterlin, N-formyl-deacetyl colchicines and new colchicine glycoside, 3-O-demethylcolchicine-3-Oalpha- D- glucopyranoside. FDA-approved use of Colchicine is to treat gout (it is one of the active ingredients of anti-gout tablets marketed by Merck&Co.). It is also used as an anticancer, antimicrobial, antifungal, anticoagulant, antilipoxygenase agent and antidote in snake bite. However, ingestion of all parts of the plant is extremely poisonous and can be fatal. The commonest clinical presentation of poisoning is severe gastroenteritis with nausea, vomiting, diarrhoea with b leading to dehydration, hypovolaemic shock and acute renal failure. Gloriosa superba usually multiply by corm and seeds but due to low germination capability it restricts for the regeneration. Therefore, in order to safeguard and preserve this important plant biotechnological approachs would be very useful. Micropropagation of Gloriosa superba meets ever increasing demands for colchicine. The availability from both wild and cultivated sources make the plant of Gloriosa superba a potential source of Colchicine in India.
