Clinical Overview
In veterinary acupuncture practice, LU9 is one of the most important points for treating respiratory disorders, cough, asthma, and vessel-related conditions.
TCVM practitioners often include LU9 in protocols aimed at tonifying the Lung, resolving phlegm, stopping cough, treating vessel disorders, and promoting Qi and blood flow.

Yuan-Source & Hui of Vessels Point
LU9 is the **Yuan-Source point of the Lung meridian**, making it the key point for all Lung disorders, especially **cough, asthma, and respiratory weakness**. It is also the **Hui-Meeting point of the Vessels (blood vessels)**, which makes it the main point for all **vessel disorders, no pulse, pulselessness, and chest pain**. As the Yuan-Source of the Lung, it tonifies Lung Qi and resolves phlegm, and as the Hui of Vessels, it regulates blood vessel function and pulse quality.

Pinpoint Location
Anatomical Landmark
On the radial end of the wrist crease, locate the radial artery (the pulsating vessel on the inner side of the foreleg). LU9 is in the depression lateral to the radial artery, at the junction of the radius and the abductor pollicis longus tendon, in the groove lateral to the artery. In dogs, palpate the wrist fold on the radial/inner side, find the pulsating radial artery, and locate the depression just beside it on the outer side.
Primary Clinical Indications
- Cough: The primary Yuan-Source point for the Lung, making it the key point for all cough, especially chronic or weak Lung cough.
- Asthma: Frequently used for asthma, wheezing, and shortness of breath. LU9 tonifies Lung Qi and resolves phlegm.
- Palpitations: Key point for palpitations, chest pain, and thoracic pain. As the Hui of Vessels, it regulates vessel function and pulse quality.
- Vessel disorders: Commonly included for no pulse, pulselessness, vocal cord dysfunction, and blood vessel-related disorders.
Recommended Point Pairings
In clinical veterinary acupuncture, LU9 is often paired with other respiratory, cough, vessel, and chest support points depending on presentation.
Frequently paired with LU1, LU5, and CV17 for cough, asthma, wheezing, and respiratory disorders. This is the classic "Source-Luo" pairing for Lung disorders.
Often combined with PC6, HT7, and CV14 for palpitations, chest pain, no pulse, and vessel disorders.
May be integrated with LU6, LI4, and CV22 for throat pain, vocal cord dysfunction, and throat disorders.
Modern Veterinary Interpretation
From a modern veterinary rehabilitation perspective, LU9 is positioned on the radial end of the wrist crease beside the artery and is highly effective for cough, asthma, palpitations, and vessel-related disorders.
Integrative veterinarians may include this point within broader respiratory, chest, vessel, and cardiac support plans involving acupuncture, electroacupuncture, and medical management.
Safety & Needling Notes
Professional Veterinary Use
Because LU9 lies directly beside the radial artery, needling must avoid the artery. Recommended technique: needle **obliquely 0.3–0.5 cun**, avoiding the radial artery. Do not needle directly into the artery.
Gentle Acupressure Guidance
Pet owners exploring supportive acupressure can use gentle, light pressure on the radial end of the wrist crease beside the artery (not on the artery itself) for 1–2 minutes per side. Avoid any pressure directly on the pulsating artery.
