Vitamin C

Why do we need vitamin C?

Vitamin C is one of several antioxidants shown to play a key role in the prevention of many types of cancers. Vitamin C maintains collagen, a protein necessary for the formation of skin, ligaments and bones. It also enhances the immune system, helps heal wounds and mend fractures, and aids in resisting some types of bacterial and viral infections.

What are some good sources of vitamin C?

Citrus fruits (oranges, grapefruit, lemons, mangos, etc.) are great sources of vitamin C, as are many green vegetables (especially asparagus, broccoli, spinach, green peppers, and peas). Other good sources of vitamin C include tomatoes, potatoes and cabbage.

What can happen if we don't get enough vitamin C?

Scurvy (hemorrages, loose teeth, gingivitis (bad breath), bone disease), bleeding gums, increased chance for infection, colds or respiratory infections can be unpleasant consequences of vitamin C deficiency.

The State of 21st Century Acupuncture in the U.S.

Whether you accept it, avoid it or live somewhere in between, insurance coverage has become a defining issue for our profession. Patients increasingly expect to use their benefits, practitioners want to be compensated fairly for their time and expertise, and the system itself remains – at best – fragmented. The encouraging news is that coverage has expanded in meaningful ways. The challenging news is that reimbursement, across the board, remains inadequate.

Vesicle Formation After Cupping: Clinical Insights & Management Considerations
Vesicle Formation After Cupping: Clinical Insights & Management Considerations

While the formation of erythema and ecchymosis is an anticipated skin response to cupping therapy, the appearance of post-treatment vesicles remains less discussed in clinical literature. This article presents a case study of vesicle formation following cupping therapy, explores underlying pathophysiology, and offers management guidelines to support practitioners in addressing this phenomenon safely and effectively.

Understanding Facial Spasms and Tics

Facial movements are essential for communication, expression and function. But when these movements become involuntary, they can lead to conditions that are not only physically uncomfortable, but also socially and emotionally distressing. Today, we’re taking a closer look at three common facial motor disorders – blepharospasm, hemifacial spasm and facial tics – and how both Western medicine and TCM view and treat them.
