All lessons Module 6: Points Lesson 12
Heart and Small Intestine: the channels and their points
Why does an acupuncturist choose HT-7 for insomnia, HT-6 for night sweating and SI-3 for a stiff neck, and what can they do with the other points of these two channels?
After this lesson you can draw both channels as a line, you know the name and category of all 28 points and the actions and indications of the key points, and you can explain why four Heart points side by side at the wrist have four different tasks.
Know by heart
- The course. Heart: from the Heart via the armpit along the little-finger side of the inner arm to the little finger. Small Intestine: from the little finger along the edge of the hand, the shoulder blade and the neck to the ear. mnemonic: where the Heart stops, the Small Intestine starts.
- Four Heart points at the wrist. HT-4 Jing-River, HT-5 Luo, HT-6 Xi, HT-7 Shu-Stream and Yuan; also HT-3 He-Sea, HT-8 Ying-Spring, HT-9 Jing-Well. mnemonic: 4, 5, 6, 7 is river, bridge, cleft, source.
- HT-7 Shenmen, Spirit Gate. Shu-Stream, Yuan; calm the Shen, sleep, nourish Heart-Blood. mnemonic: you close the Spirit Gate at night.
- The three neighbours of HT-7. HT-5 Tongli: Luo; tongue and speech, palpitations. HT-6 Yinxi: Xi; Heart-Yin, night sweating. HT-8 Shaofu: Ying-Spring; clear Heart-Fire. mnemonic: speak, sweat, scorch.
- SI-3 Houxi, Back Stream. Shu-Stream; opening point of the Du, partner BL-62; neck, back, spine.
- Small Intestine in order. SI-1 Jing-Well, SI-2 Ying-Spring, SI-3 Shu-Stream, SI-4 Yuan, SI-5 Jing-River, SI-6 Xi, SI-7 Luo, SI-8 He-Sea; lower He-Sea ST-39. Back-Shu and Front-Mu: Heart BL-15 and CV-14, Small Intestine BL-27 and CV-4. mnemonic: count from 1 to 8, the source sits at 4.
- Red flag. Chest pain, palpitations with fainting or breathlessness, or sudden loss of voice with a drooping mouth: a doctor or emergency services first (112 in Europe, 999 in the UK, 911 in North America), not a point.

Three practice questions from this lesson
Which four Heart points lie in a row at the wrist?
- HT-6, HT-7, HT-8, HT-9
- HT-4, HT-5, HT-6, HT-7
- HT-1, HT-2, HT-3, HT-4
Answer: HT-4, HT-5, HT-6, HT-7. HT-4 Jing-River, HT-5 Luo, HT-6 Xi, HT-7 Shu-Stream and Yuan: river, bridge, cleft, source.
