mineral contents of selected medicinal and stimulating,living organisms (including plants, animals and microorganisms) store and transport metals so as to get appropriate concentration for later uses in physiological reactions as well as a means of protection against the toxic effects of the metals. this paper reviews the mineral contents of medicinal and stimulating plants in ethiopia..a review on heavy metals (as, pb, and hg) uptake by plants,another advantage of phytoremediation is the generation of a recyclable metal-rich plant residue . phytoremediation could be a viable option to decontaminate heavy-metal-polluted soils, particularly when the biomass produced during the phytoremediation process could.
What Can I Do For You?
of synthetic medicines, the popularity of over the counter health foods, nutraceuticals, and medicinal products from plants or any other natural source has recently increased because of the belief that they could be more effective than conventional therapies for preventing or treating diseases. this attitude indirectly indicates the
the study explored the role of medicinal plant extracts in the fabrication of agnp. the plants extract reduced silver metal ion into elemental silver, and efficiently capped its crystallisation in the nanometre scale. the biofabricated agnp was characterised using uv–vis spectroscopy, xrd, edx, aas, fe-sem and tem.
leaves and other plant parts that are prepared properly, well-dried and stored can be used up to six months. tips on preparation for intake of herbal medicines: • use only half the dosage prescribed for fresh parts like leaves when using dried parts. • do not use stainless steel
while these actions are vitally important for protecting against natural toxins produced within the body or by animals or plants, they are perhaps even more important in the modern age to protect against the vast range of pollutants, pesticides, pharmaceuticals, heavy metals, radiation and other industrial toxicants created from human activity.
treatment with medicinal plants is considered very safe as there is no or minimal side effects. these remedies are in sync with nature, which is the biggest advantage. the golden fact is that, use of herbal treatments is independent of any age groups and the sexes.
the indian materia medica was extensive and consisted mainly of vegetable drugs, all of which were from indigenous plants. charaka knew 500 medicinal plants, and sushruta knew 760. but animal remedies (such as the milk of various animals, bones, gallstones) and minerals (sulfur, arsenic, lead, copper sulfate, gold) were also employed.
keywords. nanoparticles; gold; plant extract; photosynthesis. introduction. during the last few decades, metal nanoparticles have elicit much interest due to their distinct physical, chemical and biological properties and had become most active area of research during past few decades [1,2].owing to the interest and importance of nanoparticles many researchers have focused on the synthesis of
the hair or stainless steel wire sieve is used for separating the coarse powders. presses. the presses are made up of wood or iron. presses are used for squeezing juices from the medicinal plants, herbs, leaves, seeds, etc. and also used as ‘filter’ after the maceration and percolation process of manufacturing tinctures.
gold: the plant extract contains different biomolecules such as proteins, sugars, amino acids, enzymes and other traces of metals. these metabolites are strongly involved in the bioreduction process. the proposed reaction was au + ions reduction into metallic au o nanoparticles in the presence of metabolites and redox enzymes ( thakkar et al., 2010 ).
examples: rose, citrus and rubber, etc. advantages of asexual propagation •as resultant species formed through asexual process are genetically identical, useful traits can be preserved among them. •asexual propagation allows propagation of crops that do not possess seeds or those which are not possible to grow from seeds.
methotrexate – folate antagonist • moa: • the structures of mtx and folic acid are similar • mtx is actively transported into mammalian cells and inhibits dihydrofolate reductase • the enzyme that normally converts dietary folate to the tetrahydrofolate form required for thymidine and purine synthesis • leucovorin rescue: • administered as a plan in mtx therapy • leucovorin (folinic acid) is directly
commonly used medicinal plants in nis have been drafted based on the format of the who monographs by the experts in nis and ccee coun-tries with the support of experts, national health authorities and ngos within and also outside the nis and ccee countries. the who mono-graphs on medicinal plants commonly used in nis have been completed
the initial stage in studying medicinal plants is the preparation of plant samples to preserve the biomolecules in the plants prior to extraction. plants samples such as leaves, barks, roots, fruits and flowers can be extracted from fresh or dried plants material. other pre-preparation of plant materials such as grinding and drying also
yellow-orange hues, with a rich orange pulp. the fruit is not just delicious and healthy, but whole plant parts, fruit, roots, bark, peel, seeds and pulp are also known to have medicinal properties. the many benefits of papaya owed due to high content of vitamins a, b and c, proteolytic enzymes like papain and chymopapain which have antiviral,
it also combats fatigue and cancer, is an antioxidant and a free radical scavenger. this paper provides a review of the medicinal benefits and chemical constituents of plantago major published in
the advantages of using metal nps as colorimetric sensors for heavy metal ions in environmental systems/samples include simplicity, cost effectiveness, and high sensitivity at sub ppm levels. karthiga et al.

modern biotechnological methods like in vitro micropropagation technique hold tremendous potential for the production of high-quality plant-based medicine. they also allow to achieve the large scale multiplication of disease-free plants, faster cloning and the conservation of desired genotypes, in a very short span of time.
medicinal plants are an important source of antioxidants (rice-evans, 2004). natural antioxidants increase the antioxidant capacity of the plasma and reduce the risk of certain diseases such as cancer, heart diseases and stroke (prior and cao, 2000). the secondary metabolites like phenolics and flavonoids from plants have been
although the use of medicinal plants is as old as mankind itself, their controlled application, the isolation and characterization of active substances, started only in the early nineteenth century. it is a known fact that the extractive plant isolates and isolated active substances played a major role in the development of modern pharmacotherapy.
place the botanical extracts or plant materials (powdered, fresh or dried) in 40% to 60% proof alcohol (some use 70-80% proof lambanog), one part herb to 5 parts distilled spirits and keep in an airtight container (25 gms of material in 600 cc of spirits). stir or shake the mixture at least once a day, infusing for a period of 4 to weeks.
