Native to eastern Africa and tropical Asia, bitter orange now is grown throughout the Mediterranean region and elsewhere, including California and Florida.
Bitter orange has been used in traditional Chinese medicine and by indigenous people of the Amazon rainforest for constipation. Amazonian natives also used it for nausea and indigestion.
Today, people use various bitter orange products as a dietary supplement for heartburn, loss of appetite, nasal congestion, and weight loss. It is also applied to the skin for pain, bruises, and bed sores.
Bitter orange, used in some weight-loss products, contains synephrine, which is similar to the main chemical in the herb ephedra. Ephedra is banned by the U.S. Food and Drug Administration because it raises blood pressure and is linked to heart attack and stroke.
The National Collegiate Athletic Association (NCAA) placed synephrine (bitter orange) on its current list of banned drugs.
The fruit, peel, flower, and oil are used and can be taken by mouth in tablets and capsules. Bitter orange oil can be applied to the skin.
Bitter Orange in Health Research
Only a few studies have investigated the usefulness of bitter orange as a dietary supplement for health purposes in people.
Bitter Orange Research Summary
Applying bitter orange oil to the skin may help with ringworm, jock itch, and athlete’s foot infections.
There’s not enough scientific evidence to support the use of bitter orange for other health purposes.
Bitter Orange Safety
There are case reports of healthy people experiencing fainting, heart attack, and stroke after taking bitter orange alone or with caffeine. However, evidence regarding the effects of bitter orange (alone or combined with other substances, such as caffeine and green tea) on the heart and cardiovascular system are inconclusive.
Because products that contain bitter orange may be unsafe, pregnant women and nursing mothers should avoid them.

Type 2 diabetes (T2D) is associated with the progression of cognitive dysfunction. Physical activity benefits cognition, but no evidence from randomized clinical trials has shown whether tai chi chuan has better long-term benefits than fitness walking in cognitive function for patients with T2D and mild cognitive impairment (MCI).
To conduct an ethnobotanical survey and document the traditional anticancer and antidiabetic plants used by the local tribes of Mizoram, Northeast India.
Type 2 diabetes mellitus (T2DM) accounts for >90% of the cases of diabetes in adults. Resistance to insulin action is the major cause that leads to chronic hyperglycemia in diabetic patients. T2DM is the consequence of activation of multiple pathways and factors involved in insulin resistance and β-cell dysfunction. Also, the etiology of T2DM involves the complex interplay between genetics and environmental factors. This interplay can be governed efficiently by lifestyle modifications to achieve better management of diabetes. The present review aims at discussing the major factors involved in the development of T2DM that remain unfocussed during the anti-diabetic therapy. The review also focuses on lifestyle modifications that are warranted for the successful management of T2DM. In addition, it attempts to explain flaws in current strategies to combat diabetes. The employability of phytoconstituents as multitargeting molecules and their potential use as effective therapeutic adjuvants to first line hypoglycemic agents to prevent side effects caused by the synthetic drugs are also discussed.
Diabetes mellitus is a chronic endocrine/metabolism disease characterized by hyperglycemia arising from defects in insulin action, insulin secretion, or both. Diabetes mellitus is often complicated by visceral lesions, which can lead to serious complications and death. A variety of new agents are in development for the treatment of the disease. Astragalus polysaccharides are monomer components extracted from the Traditional Chinese Medicine, Huangqi (Radix Astragali Mongolici), which have been studied widely for treating diabetes mellitus with promising effects in recent years. This paper reviews recent advances in experimental studies on the effects of Astragalus polysaccharides in treating diabetes mellitus. The effects of Astragalus polysaccharides on the etiology and complication of diabetes mellitus including insulin resistance and secretion, diabetic neuropathy, diabetic retinopathy, diabetic cardiomyopathy, diabetic foot, and infection complicated by diabetes mellitus are discussed.
Obesity and diabetes are closely related metabolic disorders that have become major public health concerns worldwide. Over the past few decades, numerous studies have explored the underlying mechanisms of these disorders and identified various risk factors, including genetics, lifestyle, and dietary habits. Traditional Chinese Medicine (TCM) has been increasingly recognized for its potential to manage obesity and diabetes. Weight loss is difficult to sustain, and several diabetic therapies, such as sulfonylureas, thiazolidinediones, and insulin, might make it harder to lose weight. While lifestyle changes should be the primary approach for people interested in lowering weight, drugs are also worth investigating. Since some of the newer glucose-lowering medications that cause weight loss, such as glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and sodium-glucose cotransporter 2 inhibitors (SGLT2i), are additionally utilized or are under consideration for use as anti-obesity drugs, the frontier between glucose-lowering medication and weight loss drugs appears to be shifting. This review provides an overview of the literature on the underlying mechanisms of obesity and diabetes and the prospect of TCM in their management. We discuss the various TCM interventions, including acupuncture, herbal medicine, and dietary therapy, and their effects on metabolic health. We also highlight the potential of TCM in regulating gut microbiota, reducing inflammation, and improving insulin sensitivity. The findings suggest that TCM may provide a promising approach to preventing and managing obesity and diabetes. However, further well-designed studies are needed to confirm the efficacy and safety of TCM interventions and to elucidate their underlying mechanisms of action.
