Research studies have shown it to work directly on the central nervous system with analgesic effects comparable to those of morphine and codeine. Many classical Chinese herbal formulas are also commonly used to treat headache. Acute injuries are generally characterized by redness, swelling, inflammation and sharp pain. Chronic injuries are generally characterized by stiffness, numbness, discomfort and dull pain. Acute neck and shoulder problems are often caused by accidents, whiplash, improper sleeping or reading postures, and similar traumas.
Treatment consists of reducing pain, swelling and muscle spasms.
Herbal formulas are designed to dispel painful symptoms while supporting the healing process. Chronic neck and shoulder problems are characterized by pain, numbness, stiffness, discomfort, limited mobility, slow recovery or continuing deterioration. Effective treatment must focus on activating qi and blood circulation, opening the channels and collaterals, and nourishing the muscles and tendons. Corydalis is a main herb in the treatment of both acute and chronic neck and shoulder problems. In addition to having strong analgesic properties, it also has a distinctive facility for treating both acute and chronic cases of inflammation.
