The use of plants for healing is as old as humankind.
Analysis of plants found in the 60,000 year old grave of a Neanderthal man were determined to be of medicinal value.
The oldest known medical document is a 4,000 year old Sumerian clay tablet that described plant remedies for various ailments.
Before the advent of chemical drugs in the 16th century, the discovery of bark, seeds, fruits, and flowers with healing properties was communicated from generation to generation, for many millennia.
In fact, numerous synthetic medicines developed in modern times were derived from, or inspired by, the chemical constituents found in nature.
Gentle on the body and readily available, therapeutic herbs are an extremely low cost way to get relief from many ailments and illnesses.
When you grow a medicinal garden, these remedies will always be available to you, and so they also provide a better sense of self-reliance.
Here are the essential healing herbs to grow for the home apothecary:
1. Aloe Vera
Native to the Arabian Peninsula, aloe vera can be found growing wild in tropical and arid climates around the globe.

Medicinal Uses:
The gel-like substance found within aloe leaves contains 75 potentially active constituents, including vitamins A, C, and E, minerals, enzymes, amino acids, and fatty acids that provide its vast healing properties.

How to Use & Store:
To apply aloe vera, slice off a portion of the fleshy leaf. Squeeze it gently to release the juice and rub it into the skin.
Although it’s best to use aloe fresh, it can be stored for longer periods by harvesting the gel and freezing it into individual portions with an ice cube tray.
Here’s our tutorial for harvesting aloe vera gel from the plant and the many ways to use it.
Cautions:
Raw aloe should only be used topically.
Do not ingest aloe vera juice as it contains aloin – a yellowish-brown compound found along the edge of the inner leaf. Aloin may be toxic when ingested in large amounts, causing diarrhea, abdominal pain, and electrolyte imbalance.
