Another popular ingredient in the Indian spice rack, curry leaves help to stabilize blood glucose levels and impact carbohydrate metabolism. An Indian study published in International Journal of Development Research studied in detail the effects curry leaves have on diabetes type 2. According to the research data, curry leaves contain a phytochemical that can help control blood sugar level in patients with Diabetes type 2 by reducing fasting and postprandial blood sugar level. Diabetic rats given a dose of about 12gm /day for a month revealed that curry leaves may treat diabetes by influencing carbohydrate metabolism and improving liver and kidney function. Also, the amazing antioxidant properties of curry leaves can boost pancreatic cell production, thereby improving insulin function.
Sage also has some medicinal properties like most of its fellow culinary herbs. It has traits that allow it to ease sore throats as well as coughs and colds. Sage was used in Egypt during ancient times to ward off evil, snakebites and to increase the fertility in women and in India sage was used to treat sore throats and indigestion. Sage has been grown in herb gardens and kitchens since medieval times when the Romans introduced it to Europe. Today sage can be found in a wide variety of natural products being sold. This makes sage a great herb for preppers because it means they too can make these natural products. Deodorants are often made from sage because of its antiperspirant properties, and mouthwashes are common due to sage's ability to kill bacteria.
The new research in cancer treatment is to find a way to target cancer stem cells which are the cells that drive the cancer growth. Chemotherapy up to date has only had success in killing the non-stem cell cancer cells. These are the cancer cells that grow from the core stem cancer cells. The problem is when you use toxic chemotherapy to try to kill the cancer cells all you accomplish is a temporary killing of the outer layer of non-stem cancer cells. The true source of the cancer proliferation is the cancer stem cells which are not killed with chemotherapy.
Even though it's more of a spice than an herb I couldn't help but include turmeric in the list of herbs. Turmeric has a long standing tradition in Hinduism and is associated with purity and cleansing. Still today Hindu brides will take part in a ceremony where they will cover their faces in a turmeric paste before taking their vows. Marco Polo once described turmeric as being a vegetable with qualities resembling that of saffron. It wasn't until about the mid 20th century when people from the west started to recognize turmeric for its medicinal benefits. Curcumin is the main ingredient found in turmeric that gives it these benefits, the concentration of curcumin in turmeric is around 3% this is why it is more beneficial to take an extract of turmeric.
