Conservation and Natural Medicines The Doctor is Out… side

Medical research from around the world has documented the health benefits of getting out in nature. Over the years, The Conservation Foundation (TCF) has promoted using parks, forest preserves, and open spaces as an important component of everyday health. But there is another health aspect of conservation that most people overlook – the preservation of plants with a scientific basis for their medicinal value. Here is a doctor that can always see you!


Plants with Medical Uses

Since antiquity, humans have tried a myriad of plants in their attempt to survive. Some nourished them, some clothed them, some killed them, and some cured their ills or provided a sense of well-being.


Plants have been used for medicinal purposes long before the prehistoric period. Ancient Unani manuscripts, Egyptian papyrus, and Chinese writings described the use of herbs. Evidence exists that Unani Hakims, Indian Vaids, and European and Mediterranean cultures were using herbs for over 4,000 years as medicine. Indigenous cultures in areas such as Rome, Egypt, Iran, Africa, and America used herbs in their healing rituals, while others developed traditional medical systems such as Homeopathy, Ayurveda, and Chinese Medicine in which herbal therapies were used systematically. Population growth, an inadequate supply of drugs, prohibitive cost of treatments, side effects of several synthetic drugs, and development of resistance to currently used drugs have led to increased emphasis on the use of plant materials as a source of medicines for a wide variety of human ailments.


Recently, WHO (World Health Organization) estimated that 80 percent of people worldwide rely on herbal medicines for some aspect of their primary health care needs. According to WHO, around 21,000 plant species have the potential for being used as medicinal plants.


Medicinal plants are considered as a rich resource of ingredients which can be used in drug development. Moreover, some plants are considered an important source of nutrition and because of that they are recommended for their therapeutic values. Some of these plants include ginger, green tea, walnuts, aloe, pepper, and turmeric. Some plants and their derivatives are considered an important source for active ingredients that are used in aspirin and toothpaste. Apart from the medicinal uses, herbs are also used in natural dye, pest control, food, perfume, tea and so on.


Plants with Medical Uses Found in Illinois

Many people are aware of the medicinal plants of the Amazon rainforest and other tropical climates, and how preservation of those lands can potentially contribute to the advance of medical science by protecting plants with possible medical benefits.


But plants found in Illinois also have medical/herbal uses and some can be edible, as well. Here is a partial list with a brief description of some of their uses. Many thanks to Karen Bergeron and her presentation Wild Medicinal and Edible Plants of Illinois.

How TCF Helps Preserve Medicinal and Edible Plants

In its 50 years, TCF has preserved 35,000 acres in Northeastern Illinois. Along with mitigation of climate change and providing the benefits of being outdoors, conservation can also contribute to human health via the preservation of plants with herbal, medical, and edible uses. A recent inventory of plants on those lands includes many medicinal and edible plants. Many of them are not native and some considered invasive, but for edibles they are cherished by many. And their medical and herbal uses help people deal with many ailments. And who knows what benefits may be discovered in the future! Thanks to TCF’s efforts, in many ways, the doctor is outside and can always see you!


Ready to contribute to conservation efforts that help provide health benefits? Well, conservation is what The Conservation Foundation does every day. We can all do more together than we can alone. Join our collective momentum – become a member today!
