Let's talk about a very promising natural acne-fighter, berberine, and how it helped me go from this:
Berberine is an alkaloid compound that is isolated from plants such as Barberry, Goldenseal and Oregon Grape. It's been used in traditional Chinese medicine going back centuries and is currently making a resurgence as an herbal treatment for type-II diabetes, poly cystic ovarian syndrome, high cholesterol and acne.
Berberine has anti-diabetic and anti-inflammatory effects and is able to reduce glucose production in the liver:
"Berberine targets a very basic and ancient regulator of metabolism present in all animals and plants called AMP-activated protein kinase (AMPK). AMPK stimulates the uptake of glucose into the cells, improves insulin sensitivity, and reduces glucose production in the liver, which is in overdrive in patients with diabetes. It slows the release of free fatty acids, which lowers lipid levels and prevents harmful fat deposition, and boosts fat burning in the mitochondria. It also stimulates the release of nitric oxide (NO), a signaling molecule that relaxes the arteries, increases blood flow and lowers blood pressure, and protects against atherosclerosis." source: http://www.drwhitaker.com/berberine-proves-powerful-against-diabetes
In addition to the properties described above, berberine is anti-inflammatory, antibacterial and androgen-inhibiting. It suppresses acne by inhibiting the skin-cell processes that form comedones, killing the acne-causing bacteria P. acnes, suppressing sebum production and improving intestinal permeability. One clinical study has shown a 45% reduction in acne following one month of treatment.
