God has created many different types of plants on earth. Scientists found many plants, which are benefited human body. Medicine was discovered from these plants. There are many types of medicines.

Homeopathic medicines: Homeopathic medicines are drug products made by homeopathic pharmacies in accordance with the processes described in the Homeopathic Pharmacopoeia of the United States the official manufacturing manual recognized by the FDA. The substances may be made from plants such as aconite, dandelion, plantain; from minerals such as iron phosphate, arsenic oxide, sodium chloride; from animals such as the venom of a number of poisonous snakes, or the ink of the cuttlefish; or even from chemical drugs such as penicillin or streptomycin. These substances are diluted carefully until little of the original remains.

Allopathic Medicine: The term "allopathic" was invented by German physician Samuel Hahnemann (1755-1843). Allopathic is derived from the Greek allo, meaning "opposite," and pathos, meaning "suffering." Use of medicine/treatment focused on eliminating the disease or alleviating the symptoms. It is opposite of Homeopathy.
A method of treating disease with remedies that produce effects different from those caused by the disease itself

Ayurvedic Medicine: Ayurveda is a holistic system of medicine from India that uses a constitutional model. Its aim is to provide guidance regarding food and lifestyle so that healthy people can stay healthy and folks with health challenges can improve their health.
There are several aspects to Ayurveda that are quite unique:
1. Its recommendations will often be different for each person regarding which foods and which lifestyle they should follow in order to be completely healthy. This is due to its use of a constitutional model.
2. Everything in Ayurveda is validated by observation, inquiry, direct examination and knowledge derived from the ancient texts.
3. It understands that there are energetic forces that influence nature and human beings. These forces are called the Tridoshas.
4. Because Ayurveda sees a strong connection between the mind and the body, a huge amount of information is available regarding this relationship.

Home Remedies: Medicine prepared at home is called home Remedies.

Herbs: Herbs are plants. Some define the word herb as any soft, green plant. But the definition is often used as an all-inclusive term to refer to all plants that have any use, even if only for foliage in one's landscaping project.

From the beginning of time herbs have been used for food, medicine, clothing, smoking, smelling, cleaning, and many other applications. In the supermarket go to the spice section, and you have the opportunity to purchase a variety of herbs. But there are many more than what you would find there. And there are many more uses than adding flavor to your favorite recipe. Some can even be found in your backyard.

It was in about 2000 B.C. in Babylon that the first documented account of herbs appeared. It described tried and tested medicinal uses of herbs, and included reference to many herbs we still use today such as thyme and bay leaves.

Over the counter medicines: you can purchase in any drug stores: without prescription.
Creams, Vitamins, Syrup, etc.

Generic medicine
All medicines have two names:
1) Brand
2) Generic
Each medicine has a generic name to describe the ingredients. Drug companies give their medicines brand names.

Difference between brand name and Generic drugs
Usually, the difference is in the name and the price of the medicine. A generic drug must have the same active ingredients as the brand name drug in order for the Food and Drug Administration (FDA) to approve the generic. The generic drug must also be the same strength, and the same dosage form (pill, liquid, shot) as the brand name. Sometimes, generic medicines have different fillers or additives that may cause slightly different effects. Generic medicines might not look like brand name medicines. The way the generic medicine looks does not change the way it works in your body.
