Corydalin (AC)™

Overview

Corydalin (AC) is a traditional Chinese herbal formula traditionally used for short-term relief during sudden head and neck channel tightness and acute headaches, including migraine, sinus, tension, vascular, and menstrual-related headaches. In Traditional Chinese Medicine, this pattern is traditionally associated with wind-cold, wind-heat, damp-phlegm, Liver yang rising, or blood stagnation obstructing the head's channels. Corydalin (AC) is designed to help invigorate qi and blood circulation and ease temporary tightness and pressure as a complementary traditional support alongside your physician's care.

⚠️ Important: Contraindicated during pregnancy and nursing. Designed for short-term management of acute headache — once the acute episode subsides, discontinue and consider a maintenance formula such as Corydalin (CR). If persistent headache pain is not relieved by this formula, seek further medical examination to rule out structural or functional causes. If diminishing vision or vomiting accompany the headache, seek medical care immediately — a CT scan or MRI may be needed to rule out intracranial pressure from a tumor, aneurysm, or cerebral stenosis. Contains Dan Shen, which invigorates blood circulation — those on anticoagulant or antiplatelet therapy such as warfarin should use with caution or avoid this formula.

Clinical Applications & Benefits

Corydalin (AC) is traditionally used to help support comfort during:

• Sudden upper body channel tightness and acute headaches, including sinus, vascular, stress, tension, menstrual-related, and migraine headaches
• Temporary head tension presenting with traditional patterns such as wind-cold, wind-heat, damp-phlegm, and Liver yang rising
• Short-term symptomatic soothing while the underlying cause of frequent or severe headaches is addressed with your physician

Anyone with frequent, severe, or worsening headaches should be under the care of a physician for diagnosis and treatment planning. This formula is a complementary support, not a substitute for that care.

Key Herbs (TCM Data)

— Yan Hu Suo (Corydalis): the principal herb, traditionally used to activate qi and blood circulation, remove blood stasis, and relieve pain.

— Bai Zhi (Angelica Dahurica): a channel-guiding herb traditionally used to lead the formula's effect to the head, dispelling wind and exterior pathogenic factors.

— Chuan Xiong (Ligusticum Chuanxiong): traditionally used to activate blood circulation in the periphery and remove stasis.

— Ge Gen (Kudzu): traditionally used to relieve pain in the upper body and dispel wind-cold and wind-heat from the exterior.

— Dan Shen (Salvia): traditionally used to improve peripheral blood circulation and microcirculation.

Safety & Contraindications

1. Contraindicated during pregnancy and nursing.
2. Designed for short-term management of acute headache — once the acute episode subsides, discontinue and consider a maintenance formula.
3. If persistent headache pain is not relieved by this formula, seek further medical examination to rule out structural or functional causes.
4. If diminishing vision or vomiting accompany the headache, seek medical care immediately — a CT scan or MRI may be needed to rule out intracranial pressure from a tumor, aneurysm, or cerebral stenosis.
5. Contains Dan Shen — those on anticoagulant or antiplatelet therapy such as warfarin should use with caution or avoid this formula.

Dosage & Directions

Standard dosage: 3–4 capsules three times daily on an empty stomach. For severe pain, 6–8 capsules every 4–6 hours as needed. Discontinue once the acute episode subsides and consider a maintenance formula.

Supplementary formulas: For recurring upper channel tension, this formula is traditionally paired with Corydalin (CR). For head channel comfort following recent overexertion, it is traditionally paired with Flex (TMX). For stress-related upper channel tightness, it is traditionally paired with Calm or Calm (ES). For upper channel tension with neck and shoulder stiffness, it is traditionally paired with Neck & Shoulder (AC).

Holistic Nutrition & Lifestyle

Nutrition: Ice drinks and cold food are traditionally reduced, as they may constrict vessels and channels. Adequate water intake is traditionally encouraged. Caffeine is traditionally reduced gradually, as caffeine withdrawal is a common headache trigger. Foods containing tyramine — alcohol, chocolate, aged cheese, processed foods — are traditionally reduced if headaches are food-triggered.

Lifestyle: Avoiding allergens, air conditioning drafts, and direct wind exposure to the head and neck is traditionally recommended. Managing stress with massage, warm baths, and gentle exercise is traditionally recommended. Regular exercise, adequate rest, and consistent sleep habits are traditionally encouraged for overall wellness.

Case Studies

The following reflect individual practitioner experiences and traditional use; results vary and are not guarantees of outcome for any individual. All patients remained under appropriate medical or practitioner supervision.

"A woman with longstanding jaw tension and tooth grinding, consistent with Liver qi stagnation and blood stasis, used Corydalin (AC) as needed alongside acupuncture and self-massage and reported decreased tension and easier jaw movement."

"A woman with frequent upper channel tension in the form of tension and cluster headaches, consistent with qi and blood stagnation with Liver blood and yin deficiency, combined Corydalin (AC) with Corydalin (CR) and acupuncture and reported headaches became infrequent by week eight."

"A woman with sudden, intense head channel urgency in the form of acute pounding headaches of unclear cause, consistent with Liver overacting on Spleen, used Corydalin (AC) and reported headache onset was delayed or absent, later identifying lack of sleep and diet as contributing triggers."

"A perimenopausal woman with recurring, cyclical upper body tension in the form of headaches around her menstrual cycle, consistent with qi, blood, and yin deficiencies, used Corydalin (AC) at the first sign of a headache and reported the headaches were prevented from developing."

"A woman with localized head and sinus channel tightness following a migraine, consistent with qi and blood stagnation, combined Corydalin (AC) with acupuncture and reported her symptoms resolved."
