How to Clear Blockages in the Large Intestine Meridian

The Large Intestine Meridian can primarily be unblocked through massage, gua sha, moxibustion, acupuncture and exercise.

I. Massage

Massage is one of the simplest methods for unblocking the Large Intestine Meridian. Using the pad of the thumb or the knuckle, follow the course of the Large Intestine Meridian, starting from the Shangyang point on the index finger, moving upwards across the back of the hand, the lateral side of the forearm and the lateral side of the upper arm, until reaching the Jugu point on the shoulder and the Yingxiang point on the face, applying pressure or kneading. Focus on pressing key acupoints such as Hegu (LI4), Shousanli (ST36) and Quchi (LI11), applying pressure to each for 1 to 2 minutes until a sensation of soreness and distension is felt. Massage helps to stimulate the flow of qi and blood through the meridians, alleviating symptoms such as toothache, a swollen and sore throat, nosebleeds, abdominal pain and bloating, as well as constipation, which may result from meridian blockages. This can be repeated once or twice daily.

II. Gua Sha

Gua Sha involves using a gua sha board to scrape the skin’s surface, thereby unblocking meridians and expelling toxins. When unblocking the Large Intestine Meridian, apply gua sha oil to the outer side of the arm, then scrape in a single direction along the course of the meridian—from the wrist towards the elbow and shoulder. The pressure should be applied gradually, from light to firm, until red or purplish-red marks appear on the skin; however, one should not force the appearance of these marks. Gua Sha helps to improve conditions of qi stagnation and blood stasis in the Large Intestine Meridian, and can be of some assistance in relieving shoulder and arm pain, headaches, fever, and constipation caused by accumulated heat in the gastrointestinal tract. After Gua Sha, care should be taken to keep warm and avoid exposure to draughts; the next session should be carried out after an interval of 3 to 7 days.

III. Moxibustion

Moxibustion stimulates acupoints and meridians through the thermal effect produced by burning moxa sticks. To unblock the Large Intestine Meridian, one may use the ‘gentle moxibustion’ or ‘sparrow-pecking’ techniques, focusing on the Hegu (LI4), Quchi (LI11), Shousanli (ST36) and Tianshu (ST25) acupoints. After lighting the moxa stick, hold it 2 to 3 centimetres away from the skin to apply heat. Moxibustion should be applied to each acupoint for 10 to 15 minutes, until the local skin becomes flushed and a sensation of warmth is felt. The warming and unblocking effects of moxibustion can effectively dispel cold pathogens and nourish qi and blood. It is particularly suitable for abdominal pain, diarrhoea and cold hands and feet caused by cold pathogens invading the Large Intestine Meridian, or for constipation resulting from qi deficiency leading to a lack of propulsive force. Care must be taken to avoid burns during moxibustion, and it is important to stay hydrated afterwards.

IV. Acupuncture

Acupuncture is performed by a qualified TCM practitioner, who uses fine needles to stimulate specific acupoints along the Large Intestine Meridian to regulate the flow of qi and blood within the meridians. Commonly selected acupoints include Shangyang, Erjian, Sanjian, Hegu, Yangxi, Shousanli, Quchi, Binao, Jianyu and Yingxiang. The practitioner will employ different tonifying or dispersing techniques based on the patient’s condition—whether it is characterised by deficiency or excess, cold or heat. Acupuncture provides strong stimulation to unblock the Large Intestine Meridian and produces rapid results; it can effectively treat more severe meridian blockages, such as symptoms associated with acute gastroenteritis, appendicitis, frozen shoulder, facial nerve paralysis and intractable constipation. This method must be performed by a licensed practitioner and must not be carried out independently.

V. Exercise

Specific physical exercises can stretch and mobilise the muscles and tendons along the course of the Large Intestine Meridian, thereby indirectly unblocking the meridians. One may practise the ‘Single Arm Raise to Regulate the Spleen and Stomach’ posture from the Ba Duan Jin, or certain twisting postures from yoga. In daily life, one may also consciously perform more movements involving extending and rotating the arms forwards and outwards, as well as massaging the index finger. These exercises promote the circulation of qi and blood in the arms, enhance the function of the Large Intestine Meridian, and help alleviate symptoms such as weak bowel movements, abdominal distension and soreness or numbness in the upper limbs caused by prolonged inactivity and sluggish circulation of qi and blood. It is recommended to practise for 15 to 30 minutes daily, ideally until the body feels slightly warm.

Unblocking the Large Intestine Meridian is a key method in Traditional Chinese Medicine (TCM) health preservation, the core of which lies in promoting the smooth flow of qi and blood through the meridians. In addition to the professional methods mentioned above, daily self-care is also crucial. One should maintain a balanced diet, consuming plenty of vegetables, fruit and whole grains rich in dietary fibre—such as broccoli, celery and oats—whilst avoiding excessive intake of spicy or greasy foods to reduce the burden on the gastrointestinal tract. Maintain a regular sleep schedule and avoid staying up late, as the night is the period when qi and blood flow through the Large Intestine Meridian. Develop the habit of having regular bowel movements and avoid holding them in for too long. It is important to maintain a calm state of mind, as anxiety and stress can disrupt the flow of qi, potentially leading to impaired transmission in the Large Intestine Meridian. If, after self-care, symptoms such as constipation, abdominal pain or pain in the shoulders and arms persist or worsen, you should seek medical attention promptly. A TCM practitioner will then carry out a pattern differentiation and treatment to formulate a personalised treatment plan.
