History of Medicinal use
Goldenseal has developed an excellent reputation for its many medicinal uses and it is rapidly growing in popularity especially in the North American market because of its natural antibiotic abilities as well as its ability to enhance the immune system.
Despite its recent popularity, goldenseal has a much longer tradition dating back many centuries.
Native Americans have been using goldenseal for a very long time indeed for a variety of health purposes including respiratory, digestive and urinary tract complaints. Goldenseal roots were used by the Cherokee to make a wash to treat inflammation, treat dyspepsia and improve appetite.
Another tribe – the Iroquois used a decoction made from goldenseal root to treat a variety of ailments including whooping cough, fever, and pneumonia. They also used it to aid digestive complaints like diarrhea, flatulence as well as to treat liver and heart disease. And that’s not all; the Native Americans prepared a concoction from goldenseal and other native roots to treat earaches and eye complaints.
By the late 18th century, goldenseal had started to gain attention as a potent healing herb and news of its virtues rapidly spread beyond the US to England and other European countries and by the mid-19th century, it had already become an important commercial product. In both America and in Europe, people were regularly taking goldenseal to aid with digestive complaints and to improve appetite.
It was also regularly used for inflammatory skin conditions and eye problems like conjunctivitis. Other traditional uses included the treatment of peptic ulcers, colitis, and dyspepsia. Because of its appetite stimulant effect, it has been used to help those recovering from illness and to treat those suffering from anorexia nervosa.
Goldenseal packs a powerful punch when it comes to essential minerals and vitamins. It contains minerals such as iron, calcium, and manganese as well as vitamins A, C, E and B complex.
The root and rhizomes used to make its medicinal supplements contain a variety of important isoquinoline alkaloids such as hydrastine, canadine, candaline and most significantly berberine. Experts believe that the alkaloid content of goldenseal is responsible for many of its natural benefits.
Modern Uses and Benefits of Goldenseal
The many traditional uses of goldenseal and its popularity today can largely be attributed to the natural medicinal qualities it contains such as the antibiotic, astringent and anti-inflammatory properties. Because of these properties, goldenseal is a very good natural and generally safe option when dealing with a wide variety of illnesses.
For respiratory conditions and sinusitis
If you are suffering from the common cold or feel that you might be coming down with the flu, goldenseal is an effective natural remedy. This herb is known to boost the immune system and a strong immune system can protect you against seasonal illnesses like cold and flu.
Goldenseal has the necessary nutrients and medical properties to curtail your sickness before it gets any worse. Goldenseal can also help soothe your mucous membranes so try using a diluted tincture as a gargle or enjoying a cup of goldenseal tea to relieve your sore throat. The same properties that help with colds may also be effective in treating symptoms of sinusitis because it can help loosen the mucus which is clogging up the sinuses.
Goldenseal has been traditionally used to treat infections of the skin and a study published in 2012 has done a lot to confirm the efficacy of this traditional use. The study was designed to examine the ability of goldenseal to combat the dangerous staphylococcus aureus virus better known these days as MRSA.
The researchers concluded that goldenseal possessed potent antibacterial properties which were effective against MRSA and lent support to its traditional use. (1) Because of these antibacterial qualities, goldenseal may prove effective in treating minor wounds, cuts and certain skin complaints.
May help treat cancer
The search for a cure for cancer is ongoing and many researchers have looked to nature to find a way of treating this terrible disease. According to research, the berberine found in goldenseal holds a great deal of potential when it comes to treating cancer.
Multiple studies have found that berberine induced apoptosis in cancer cells meaning that they cause the death of casncer cells while leaving healthy cells untouched. One in vitro study for example found that berberine was able to inhibit the growth and spread of cancer cells more effectively than a chemotherapy drug called doxorubicin. (3)
Other in vitro studies have revealed that berberine was effective against cancerous brain tumor cells. One study comparing the effects of berberine against a chemotherapy drug called carmustine was extremely promising. The researchers found that berberine had a 91% cancer kill rate compared with carmustine at 43% (4)
We can only hope that research continues to show that natural compounds like berberine has a major part to play in treating cancers.
For the heart
The Native Americans also traditionally used goldenseal for a variety of heart conditions but is there any truth to this traditional use? Well apparently there is; researchers in a study published in 2006 set out to examine the effects of goldenseal on cholesterol levels. One of the alkaloids contained in goldenseal called berbetine.
Berbetine is already known to have cholesterol reducing effects and researchers were keen to find out whether the herb was as effective. The results were very positive with the researchers concluding that goldenseal root extract was an effective treatment to reduce levels of LDL or bad cholesterol. (2)
