Gentle Lax (Deficient)™

TCM herbal formula for chronic, habitual, and deficient-type constipation with dry hard stools — emollient; laxative; moistens intestines; unblocks bowels; drains heat; nourishes yin and blood. Suitable for postpartum, postsurgical, convalescing, and geriatric patients. Also effective for drug-induced constipation from opioids and antipsychotics.

⚠️ Contraindicated during pregnancy and nursing. Individuals with sensitive GI tracts should reduce dosage and take with food. Suspect a more serious etiology if constipation is accompanied by vomiting, blood in stools, weight loss, or distended tympanitic abdomen — refer to a physician. Contains Da Huang (Radix et Rhizoma Rhei) — California Prop 65 warning: "This product contains Da Huang (Radix et Rhizoma Rhei). Read and follow directions carefully. Do not use if you have or develop diarrhea, loose stools, or abdominal pain because Da Huang may worsen these conditions and be harmful to your health. Consult your physician if you have frequent diarrhea or if you are pregnant, nursing, taking medication, or have a medical condition." Contains Dang Gui Wei (Extremitas Radix Angelicae Sinensis) — patients on anticoagulant or antiplatelet therapies such as Coumadin (warfarin) should use with caution or not at all. Prolonged use of Da Huang is not recommended — may increase risk of habitual constipation and fluid/electrolyte imbalance. Note on Zhi He Shou Wu: this formula uses the prepared form (Zhi He Shou Wu / Radix Polygoni Multiflori Praeparata), which is a safe tonic herb — not the unprepared form (Sheng Shou Wu), which carries risk of nausea, vomiting, abdominal pain, diarrhea, and rare dose- and time-dependent reversible liver disorder. Due to medical risks and legal liabilities, exercise caution and do not use either form in patients with pre-existing or risk factors of liver disease.

CLINICAL APPLICATIONS

* Constipation

* Chronic, habitual constipation with dry, hard stool

* Deficient-type constipation in postpartum, postsurgical, or convalescing individuals

* Mild colon cleanser

Background: Constipation is the infrequent or incomplete passage of stools — usually dry and hard, difficult to pass even with straining, with two or fewer bowel movements per week and feelings of incomplete evacuation. Common causes include lack of exercise, insufficient water and fiber intake, stress, overuse of laxatives, and use of certain drugs (opioids, antipsychotics, antidepressants, anticholinergics). Deficient-type constipation is defined as chronic or habitual constipation, constipation in geriatric patients, or constipation in patients with red tongue, pale or sallow face, and general signs and symptoms of weakness.

Key herb-level clinical data:

— Da Huang (Radix et Rhizoma Rhei / Rhubarb Root): direct laxative and purgative — quickly and powerfully treats constipation; works mainly on the transverse and descending colon by inhibiting re-absorption of water and causing evacuation of stool; increases peristalsis of the large intestine without interfering with nutrient absorption in the small intestine; see California Prop 65 warning above

— Yu Li Ren (Semen Pruni / Bush Cherry Seed / Prunus Japonica Seed): increases peristalsis; promotes bowel movement; moistens intestines; unblocks bowels

— Bai Zi Ren (Semen Platycladi / Arborvitae Seed / Biota Seed): mild lubricant effect — lubricates bowel and relieves constipation; moistens intestines

— Zhi Shi (Fructus Aurantii Immaturus / Immature Bitter Orange / Chih-shih): stimulates smooth muscle; increases intestinal peristalsis; dissipates stagnation; reduces distension and bloating

— Hou Po (Cortex Magnoliae Officinalis / Magnolia Bark): dissipates stagnation; reduces distension and bloating; clinical study: 36 women — greatly reduced incidence of constipation and abdominal bloating following surgery

— Jue Ming Zi (Semen Cassiae / Cassia Seed / Semen Cassiae Obtusifoliae): moistens intestines; facilitates passage of stools; clinical study: used as tea throughout the day — marked effect to relieve chronic constipation

— Ku Xing Ren (Semen Armeniacae Amarum / Bitter Apricot Seed / Apricot Kernel): lubricates the Large Intestine; directs qi downward

— Tao Ren (Semen Persicae / Peach Seed / Persica Seed): lubricates the Large Intestine; directs qi downward

— Xuan Shen (Radix Scrophulariae / Scrophularia / Figwort Root): clears heat; cools the blood; nourishes yin

— Mai Dong (Radix Ophiopogonis / Ophiopogon / Dwarf Lilyturf Root): clears heat; nourishes yin

— Bai Shao (Radix Paeoniae Alba / White Peony Root): nourishes blood; relieves pain associated with constipation; clinical study: 60 patients with chronic habitual constipation treated with Bai Shao + Gan Cao and others — great success

— Dang Gui Wei (Extremitas Radix Angelicae Sinensis / Angelica Sinensis Tail): enriches blood; gentle laxative — moistens desiccated intestines; caution with anticoagulants

— Zhi He Shou Wu (Radix Polygoni Multiflori Praeparata / Prepared Fo-Ti / Prepared Polygonum): enriches blood; gentle laxative — moistens desiccated intestines; prepared form is safe and well-tolerated (Maillard reaction during processing significantly changes chemical composition, generates new compounds, alters sugars and 16 amino acids, reduces pH from 6.28 to 5.61 — eliminating adverse reactions of the unprepared form)

Nutrition: Eat plenty of high-fiber foods — fresh fruits, green leafy vegetables, cabbage, peas, sweet potatoes, and whole grains. Drink at least 8 glasses of water daily. Prunes or prune juice are very effective for mild constipation. Wild or raw honey with fresh grapefruit relieves dry stool. Black sesame with wild honey softens stool and facilitates bowel movement. Increase nourishing cooling roots: Mexican yam, yam, radishes, potatoes, carrots, melons, cucumbers, beets, turnips, malanga, celeriac, taro, rutabaga. Avoid deep-fried, fatty, and spicy foods. Avoid spicy/pungent/aromatic vegetables: pepper, garlic, onions, basil, rosemary, cumin, fennel, anise, leeks, chives, scallions, thyme, saffron, wormwood, mustard, chili pepper, wasabi.

Tao of Nutrition (Dr. Maoshing Ni and Cathy McNease): Recommended foods: bananas, apples, walnuts, figs, spinach, peaches, pears, pine nuts, sesame seeds, mulberries, grapefruit, yams, honey, apricot kernel, milk, yogurt, alfalfa sprouts, beets, cabbage, bok choy, cauliflower, and potato. Eat 2 bananas on an empty stomach followed by a glass of water. Drink a glass of lukewarm water with 2 teaspoons of honey on an empty stomach. Drink blended beets and cabbage on an empty stomach. Eat 5–10 figs on an empty stomach followed by a glass of water. Eat a fresh apple on an empty stomach daily. Drink mulberry juice. Eat lightly steamed asparagus and cabbage at night before retiring. Avoid spicy foods, fried foods, and meat.

Lifestyle: Avoid stress, anxiety, and tension. Exercise regularly to increase intestinal peristalsis — walking massages the intestines and regulates bowels. Do not suppress the urge to relieve the bowels — suppressing is one of the main causes of chronic constipation; empty bowels whenever there is a desire, especially in the morning when the digestive system is most active. Massage the abdomen clockwise along the directional flow of the large intestine. Patients with hemorrhoids should not lift anything heavy.
