The Medicine
Mainly the medicines of homeopathic are derived from vegetable, mineral and animal sources. 
Some of them has high poisonous in their original, undiluted form and the person or patients who use it sometimes feeling apprehensive, but the method of homeopathic medicine for preparation yields such extremely high dilutions that there is never a danger of toxicity.
Another important group are the “nosodes“, it’s derived from disease products.
They can be given for symptoms that persist after recovery from the disease in question - the “never well since” clinical picture.
Some of the nosodes have been used so widely that they have taken on the status of independent homeopathic medicines and are prescribed on the basis of symptoms even when there is no history of the disease they are related to.
Homeopathic medicine may be given in liquid form or, more usually, as sugar pills or powders. Sometimes they are given as a single long-acting dose, or else they may be given once a day or more frequently for days or weeks.
They should be allowed to dissolve under the tongue.
It is often said that patients taking homeopathic medicines should avoid drinking tea or coffee, but there is no good evidence that these substances really interfere with treatment.
However, minimizing coffee intake in general is a well researched nutritional consideration.
It is probably enough to avoid eating or drinking for 10 to 20 minutes before and after taking the medicines.
There is no good evidence that conventional drugs interfere with homeopathic medicines.
In any case, it is always undesirable to stop any prescribed treatment without the approval of your medical doctor (M.D.).
There are no known dangerous interactions between homeopathic medicines and conventional drugs.
The principal claim made by homeopathic doctors is that their treatment is safe, and this is true, provided that no serious disease process or pathology has been overlooked and that conventional treatment is not withdrawn unadvisedly.
To reiterate, there are no dangerous interactions between homeopathic medicines and conventional ones.
Vitamin/Mineral
Vitamins and minerals are essential to life.
They contribute to good health by regulating the metabolism and assisting the biochemical processes that release energy from digested food.
They are apart of a class of micronutrients called coenzymes which act to assist enzymes in their function to make food available to our bodies.
Vitamins are considered micronutrients because the body needs them in relatively small amounts compared with nutrients such as carbohydrates, proteins, fats and water.
Orthomolecular medicine is the treatment of disease using vitamins in large quantities to act therapeutically or in some cases replace an existing deficiency.
Minerals are needed for the proper composition of body fluids, the formation of blood and bone, the maintenance of healthy nerve function. They are also used in the regulation of muscle tone, including that of the muscles of the cardiovascular system.
Like vitamins, minerals work as coenzymes, enabling the body to perform its functions, including energy production, growth, and healing. Because all enzyme activities involve minerals, they are essential for the proper utilization of vitamins and other nutrients.
Herbs
Herbs are essentially “natural” drugs.
Theoretically, botanical medicines have similar therapeutic uses to the medicines that exist in the conventional drug world but with a fraction of the potency and with the bonus of a “holistic” action. This means that the plants active ingredients are not the only ingredients that play a role in healing. The majority of today’s herbal remedies and photochemicals exhibit varying degrees of therapeutic value. Some such as ginkgo, valerian, and saw palmetto; seem genuinely useful, while others- such as ephedra and nightshade- can actually be dangerous.
As the use of unfamiliar botanicals spreads, the need to steer patients towards the few truly useful preparations, warn patients away from ineffective and dangerous alternatives, and limit the overuse of botanicals will be my priority when it comes to herbal therapeutics.
Homeopathy
The science and art of homeopathy embody what many people envision as a 21st century medicine. Homeopathy is a medical approach that respects the wisdom of the body. It is an approach that utilizes medicines that stimulate the bodies own immune and defense system to initiate the healing process.
It is an approach that individualizes medicines according to the totality of the person’s physical, emotional, and mental symptoms.
It is an approach that is widely recognized to be safe. And it is an approach that can be potentially very effective in treating the new types of diseases that are afflicting us now and will affect us in the 21st century.
