Acupuncture is a traditional Chinese medicine (TCM) that has been practiced for thousands of years. It has been helpful for many physical and mental conditions, including pain management for headaches, back pain and arthritis. It's also used to address issues like stress, anxiety, digestive disorders, and even infertility.

Acupuncture works in various ways:

• Meridians and Qi Flow: Traditional Chinese Medicine identifies 12 main meridians through which Qi flows. Each meridian is associated with specific organs and functions. Acupuncture points along these meridians are stimulated to balance the flow of Qi.
• Acupuncture Points: There are hundreds of acupuncture points on the body, each linked to a particular function or organ system. Inserting thin, sterile needles into these points is believed to correct imbalances and restore the flow of Qi.
• Holistic Approach: TCM views health as a balance between the body, mind, and spirit. Acupuncture aims to address not just physical symptoms but also emotional and mental imbalances.

There are various techniques associated with acupuncture:

• Needles: Acupuncture needles are typically thin, solid, and metallic. They're inserted into the skin at specific depths, depending on the condition being treated. Sensations during needle insertion can vary from a slight tingling to a dull ache.
• Moxibustion: This technique involves burning an herb (moxa) near or on the acupuncture points to warm and stimulate them.
• Cupping: Cups are placed on the skin to create a vacuum, promoting blood flow and easing muscle tension.
• Acupressure: Pressure is applied to acupuncture points using hands, fingers, or devices instead of needles. 

The practice is generally considered safe when performed by a trained and licensed practitioner using sterile needles. It's essential to consult with a qualified professional if you're considering acupuncture as part of your healthcare regimen.
