Natural antibacterial

Home remedies offer an inexpensive and safe option for treating skin diseases. Eor example, regularly washing the face with a face wash that contains tea tree oil, a natural antibacterial agent, helps to kill the bacteria residing in the pores of the skin and helps to reduce instances of acne. Epsom salt baths or mud baths coupled with frequent exposure to sunhght are excellent home remedies for psoriasis. The application of oatmeal or seawater can help reduce the inflammation and itchiness associated with eczema. 

Diazaquinomycin A 123 is a natural antibacterial agent isolated from a Streptomyces strain and has been synthesized by Avendafio and co-workers <1998TL673> (for previous syntheses, see <1996CHEC-II(7)921>). 6-Azapinanaomycin A methyl ester 124 and 6-azaeleutherin 125 have been shown to be effective antibiotics <1997S567>. 

Lysozyme is a natural antibacterial agent found in tears and egg whites. The hen egg white lysozyme (Mr 14,296) is a monomer with 129 amino acid residues. This was the first enzyme to have its three-dimensional structure determined, by David Phillips and colleagues in 1965. The structure revealed four stabilizing disulfide bonds and a cleft containing the active site (Fig. 6-24a see also Fig. 4-18). More than five decades of lysozyme investigations have provided a detailed picture of the structure and activity of the enzyme, and an interesting story of how biochemical science progresses. 

Honey is not only just a natural sugar substitute, but also certain strains of honey can actually help to heal wounds and kill bacteria. Honey has been used to prevent and cure illness for centuries. The Chinese used it to neutralize toxins and relieve pain, treat stomach ulcers, high blood pressure, and constipation. It is also perfect for dabbing onto bums and wounds to help heal the tissue Not all honeys are equal in their goodness. New Zealand Manuka honey is one of the best, as it is harvested from native tea trees, a natural antibacterial agent in itself. 

Industrial separation membranes and ion-exchange resins can be made from chitin, especially for water purification. Chitin is also used industrially as an additive to thicken and stabilize foods and pharmaceuticals. Since it can be shaped into fibres, the textile industry has used chitin, especially for socks, as it is claimed that chitin fabrics are naturally antibacterial and antiodour (www.solstitch.net). Chitin also acts as a binder in dyes, fabrics and adhesives. Some processes to size and strengthen paper employ chitin.

C3 and C4 components are natural antibacterial agents present in human colostrum. Sepehri et al. (1998) reported that pectin-rich plant extracts enhanced transfer of C3 and C4 from blood to colostrum by an unknown mechanism. This observation suggests that these plant extracts may be used to reinforce the antibacterial activity of human colostrum. 

Proteins from marine sources show promise as functional ingredients in foods because they possess numerous important and unique properties such as film and foaming capacity, gel-forming ability, and antimicrobial activity (Table I). Some of the most prevalent marine proteins used in foods are collagen, gelatin, and albumin, all of which can be extracted from fish and seafood by-products. The protein protamine has also shown promise for use in the food industry as a natural antibacterial preservative. 

Hemp fibers are obtained from the bast of the plant. These fibers exhibit natural antibacterial properties and conduct heat. Because of the low lignin content hemp fibers are mainly used in the paper industry. 

Biological reaction products are often of therapeutic interest for instance, penidUin is a metabolite of Aspergillus and Penicillium spedes, produced under stress conditions, exerting a strong antibiotic activity. In fact, natural antibacterial activity is often carried out by specific molecules that organisms produce under bacterial attack this happens frequently in plant systems, where the immunological response is primarily the cells release of poisons to defeat bacterial infection.
