Catnip
“Catnip” is the common name for a perennial herb of the mint family. Catnip is native to Europe and is imported into the United States. In North America it is a common widespread weed. Catnip is most popular with cats and the reaction that it causes in them when they receive some dried nip from their owner. They roll around in it in all of their glory. The fact is that humans do not smell what cats smell when it comes to catnip so humans do not react the same way that cats do. It is known that the chemical nepetalactone in catnip is the thing that triggers the response. Apparently, it somehow kicks off a stereotypical pattern in cats that are sensitive to the chemical.
In humans catnip has been used for several ailments including the treatment of colic, headache, toothache, colds, and spasms. It is also known to induce sleep in most people but it others it can have a counter effect. Catnip also has antibacterial properties to it too. In the 15th century the English cooks would season meats with catnip and also add a pinch to salads. Many people also prefer catnip tea to Chinese tea. Some of the agents in catnip also act as a very effective cockroach repellent. It has actually been proven to be more effective by 100% than DEET.
Burdock
Burdock is a plant that is related to the daisy family. It is also closely related to Echinacea, Dandelion, and Feverfew. Burdock is an herb but it is one that has been much neglected when it comes to getting attention. Back in ancient times the Greeks used the roots, the seeds, and the greens and used them for healing purposes. Throughout the Middle Ages Burdock was used for both food and medicine.
Today, Burdock is still used for such things as easing liver problems and digestive disorders. It was also found to be very effective for cleansing the skin for problems such as acne and also to assist in digestive problems. To this day throughout Europe the stalk and the greens are still eaten because they hold such valuable nutrition and vitamin values.
Belladonna
Belladonna is not an herb that you are going to want to stock your pantry with. While it has its benefits, this is an herb that can be very dangerous and sometimes even fatal. It has some medicinal properties to it and has an interesting history but it can be very dangerous. The nickname “deadly nightshade” is a good clue of its potency. There is however a tincture that comes from this plant that is used for medicinal purposes. Belladonna is a perennial herb that is native to Europe and Asia Minor but is now grown quite often in the United States, Europe, and India. When the plant is in full bloom the plant is harvested and then dried for use.
Basil
Originally, Basil was not the most popular herb in the bunch. Actually there were some who simply hated it, mainly the ancient people. 
The name basil means “be fragrant” but still various cultures battled with a love hate relationship over basil. Americans and Romans loved it while Hindus plant it in their homes as a sign of happiness. On the contrary it was the Greeks who despised it most but those from India and Persia were not too fond of it either. One place that took a special liking to Basil was Italy and to this day not many people prepare a classic pasta sauce without the Basil.
Balsam of Tolu
Balsam of Tolu is an herb that comes from a very tall tree that can be found in Columbia, Peru, Venezuela, Argentina, Brazil, Paraguay, and Bolivia. This herbal plant has also been called Balsam of Peru because it was originally exported primarily from Peru but that is no longer the case. The resin of this tree is what is most valuable and is retrieved in the same fashion that one collects the valuable properties from a rubber tree by tapping into it. The gummy resin that comes from the tree is then turned into balsam. Today, the main exporters of Balsam of Tolu are El Salvador, Columbia, and Venezuela.
Asafoetida
Asafoetida has been also referred to as the “Food of the Gods.” 
The main part of this plant that is used is the resin which makes up a volatile oil. The history of this herb is amazing as it was used frequently back in time by Alexander the Great for flavoring. That was back in 4 B.C. still in early times, Asafoetida was used to treat gas and the bloating associated with it. Carrying through time the resin gum is used often for vegetarian dishes that are prepared in India. Today, it is one of the main flavorings in Worcestershire sauce.
Alfalfa
Alfalfa, which is a perennial herb, has a long list of dietary and medicinal uses and research has proven that Alfalfa might lower blood levels of cholesterol and glucose. Many take Alfalfa supplements orally and is has been proven safe except in a small percentage of people where it produces lupus like symptoms. In the seeds and sprouts of Alfalfa, amino acid L-canavanine is present and that is what is thought to cause this reaction. However, this is not present in the leaves of the Alfalfa. The whole leaf and the herb are what are rendered from the Alfalfa plant.
