There is no going back on the fact that plants and plant extracts have been serving man since the beginning of time. Before the advent of synthetic drugs, natural plant products have been key in the maintenance of the health of individuals. Up till today, herbs, as some people commonly call it, represent a major source of the drug for treating ailments in some people and several anecdotal and scientific evidence exist to prove their efficacies.
Even though as of today, herbal treatment of ailments is kind of limited to a section of the population in the underdeveloped and developing countries of the world (and some enthusiasts in developed countries as well), there exist several advantages in the use of herbs over synthetic drugs.
Disease-causing organisms, also known as pathogens, sometimes mutate and develop resistance to drugs. The hope of humanity lies in the continuous search for more advanced options to keep up with the rate of evolution of pathogens. The world's plant biodiversity represents a huge pool for future drug discovery for the treatment of diseases caused by evolving pathogens.
One popular method of utilizing plants for medicinal purposes is the consumption or topical application of their extracts. Although refined extracts are generally considered to be safer than crude extracts, the latter remains the primary mode of consumption for several local people. In Nigeria, below are the most common methods of preparing herbal extracts locally:
Water is generally referred to as a universal solvent and as such, it is one of the most widely used liquids used in the dissolution of solutes. Aqueous preparation of plant extracts varies depending on the state of the plant materials - whether it is in dry form for fresh form.
Aqueous herbal preparation in some quarters makes use of hot water in order to further increase entropy and aid extraction.
Instead of using water, some prefer to use solvents that are alcohol-based. Water is a polar solvent and will readily extract polar molecules while alcohol is less polar and is able to extract less polar molecules.
Alcohol-based solvents are sometimes used to extract plants in ways similar to how water is used. The solvent to be used, however, must be one that is non-toxic to humans. Several commercial herbal mixtures sold around here are alcohol-based and provides a two-in-one opportunity to treat ailments as well as get 'high' for those that love to do so.
Some of the alcohol-based solvents commonly used include locally fermented gin, palm wine, commercial gins, and so on.
It does not matter how technologically advanced the entire world is, plants have been, and remain to play important roles in the health and overall well-being of humans.
Herbal extracts consumption remains one key way in which plants are utilized in the treatment of ailments. Preparation of extracts can be done using water or alcoholic drinks as the solvent for extraction. Each solvent presents its advantages. While water will extract water-soluble contents of plants, alcohol will extract less water-soluble contents with some degree of overlapping in the ability of the two solvents.
Extraction can be done by using fresh or dry plant materials. Extractions done using fresh plant materials are usually ready for consumption almost immediately while those done using dry materials can take days before the extraction is completed and the extract ready for consumption.

Always do your own research before consuming plant extracts for therapeutic purposes. Better still, always consult your physician if you feel unwell.
