Now modern science has confirmed that it has impressive benefits for several different health problems.Alkaloids are normally alkaline and colourless but berberine is acidic in nature and identified by its bright yellow colour. Historically it has been used as a yellow dye in a number of countries. It has many actions in the body including anti-inflammatory, anti-tumour and broad spectrum antimicrobial against bacteria, fungus, viruses and parasites. It is powerful enough to target antibiotic resistance to have long term health benefits and it will reduces the chances of catching the flu or the viral cold due to bacterial infection. Berberine is one of the few compounds known to activate AMPK-Adenosine Monophosphate activated Protein Kinase, it is an enzyme inside the human body plays a crucial role in regulating metabolism, AMPK activation boosts fat burning in the mitochondria. It aids in tissue repair, maintaining a healthy heart rhythm and to control lipid and blood sugar regulations, it is normoglycemic due to AMPK activation. It blocks proprotein convertase subtilisin kexin 9 (PCSK9), which plays a key role in metabolism of lipoprotein. Berberine having inhibitory effects on the proliferation and reproduction of certain tumorigenic microorganisms and viruses such as hepatitis B virus and helicobacter pylori. According to some studies berberine works by inhibiting an enzyme called PCSK9.This leads to more LDL being removed from the blood stream. It increases energy expenditure, limits weight gain, improves cold tolerance and enhances brown adipose tissue activity. It was shown to reduce blood pressure by competitively inhibiting vascular smooth muscle cells α1 receptors, thereby blocking the release of the enzyme adenylyl cyclise. It promotes optimal joint health; according to 2017 berberine significantly improved joint health in rats. Berberine improves gastrointestinal and immune health by protecting mucous membrane throughout the body and it is able to fight against severe damage like that induced by heavy alcohol consumption. It also promote high bone mineral density, regular consumption of berberine improved the bone mineral density in male and female mice. Several studies have also suggested that berberine may support optimal mental health as we age. Regular consumption of berberine can increase brain chemicals such as dopamine, serotonin, and norepinephrine, which are essential for healthy brain function and maintaining a positive mood. For women with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization, berberine has been shown to be more effective than metformin in achieving live births with fewer side effects. Additionally, pre-treatment with berberine significantly reduces cigarette smoke-induced acute lung inflammation due to its anti-inflammatory properties.

Pharmacological Properties of Berberine

Berberine is a bioactive compound with a wide range of pharmacological properties that have garnered significant attention in recent years. One of its most important mechanisms of action is the activation of AMP-activated protein kinase (AMPK). AMPK is a critical regulator of cellular energy metabolism, and its activation leads to enhanced glucose uptake and lipid oxidation. This makes berberine particularly effective in the management of metabolic disorders, including type 2 diabetes and obesity. Research indicates that berberine can significantly lower blood glucose levels and improve insulin sensitivity. In clinical trials, it has been shown to reduce fasting blood glucose levels and hemoglobin A1c, making it a viable alternative or adjunct to conventional diabetes treatments. Its ability to modulate lipid metabolism is equally impressive; berberine has been found to decrease levels of low-density lipoprotein (LDL) cholesterol, often referred to as "bad cholesterol," while simultaneously increasing high-density lipoprotein (HDL) cholesterol, known as "good cholesterol." This dual action contributes to better cardiovascular health and helps mitigate the risk of atherosclerosis. In addition to its metabolic benefits, berberine exhibits strong anti-inflammatory and antioxidant properties. Chronic inflammation is a significant contributor to various health issues, including heart disease and certain cancers. By reducing pro-inflammatory cytokines and inhibiting inflammatory pathways, berberine can help alleviate these conditions. Furthermore, its antioxidant effects help protect cells from oxidative stress, enhancing overall cellular health.
