Anal Fissure

What is Anal Fissure?

An anal fissure is a longitudinal tear in the skin of the anal canal below the dentate line, the point where the lining changes from rectal to anal skin. It is a common problem in both adults and children.^[1] Most fissures start with local injury to the skin, often from a hard or bulky stool, and they are more frequent in people with chronic constipation.^[1]

Common symptoms

The typical symptom is sharp pain during a bowel movement, often followed by a burning or aching pain afterward.^{[1, 2]} Bright red bleeding on the stool or tissue is also common.^[2]

Fissures are called acute when symptoms last under 6 weeks and chronic when they last longer. Chronic fissures often show a skin tag at the outer end or a small swollen papilla at the inner end.^[1]

Causes and risk factors

Most fissures are linked to a tight anal sphincter muscle, and hard stools are a common trigger but are not present in every patient.^[3] Other triggers include repeated irritation, anal surgery and anal intercourse.^[1]

Fissures that sit to the side or occur in multiples are called secondary. They can point to another condition such as Crohn disease, tuberculosis, infection or cancer and need further evaluation.^{[1, 4]}

How it is diagnosed and treated conventionally

Diagnosis is usually made from your history and a gentle examination.^{[1, 4]} Initial treatment is more fiber and fluids, plus comfort measures such as warm sitz baths.^{[2, 3]} About half of patients heal with non-surgical care.^[3]

Chronic fissures may need prescription ointments that relax the sphincter or botulinum toxin injection. A Cochrane review of 75 trials found that nitroglycerin ointment healed slightly more fissures than placebo (48.9% against 35.5%), that recurrence was common, and that no medical treatment matched the healing rate of surgery.^[5] A 2025 network meta-analysis of 22 trials ranked topical nifedipine highest for healing.^[6] Lateral internal sphincterotomy is the standard surgical treatment.^[2]

Why Anal Fissure calls for a whole-person approach

An anal fissure is a local tear, but what keeps it from healing involves the whole bowel and the muscle around it. Stool consistency, sphincter tension and any underlying bowel disease can each matter.^{[1, 3]}

This is why care that looks at digestion and daily habits as well as the wound itself is a reasonable companion to medical treatment.

Stool consistency and constipation

Hard or bulky stools are a leading cause of the original tear, and fissures are more common in people with chronic constipation.^[1] High fiber and fluid intake is the first step in conventional care.^[2]

Sphincter muscle tension

Most fissures are associated with raised pressure in the internal anal sphincter, and many medical and surgical treatments work by lowering it.^{[3, 5]}

Underlying bowel conditions

When a fissure is off the midline, multiple or slow to heal, doctors look for conditions such as Crohn disease or infection.^{[1, 4]} Treating the underlying condition is the main route to healing in these secondary fissures.^[1]

Acupuncture for Anal Fissure

What the research shows

The research on acupuncture for anal fissure is limited. A PubMed search found no systematic reviews and no sham-controlled trials. Two small randomized trials, both from China and published in a Chinese journal, compared acupuncture-related treatment with medicines.

In one trial of 200 patients after fissure surgery, acupuncture at points on the lower back plus moxibustion near the tailbone was compared with an oral laxative. From the third day, defecation pain was lower in the acupuncture group, but stool difficulty and stool texture did not differ.^[7] In the other trial, 60 patients with early-stage fissures received weekly acupoint catgut embedding, in which absorbable thread is placed at acupuncture points, or a nitroglycerin ointment. The embedding group had lower pain scores and fewer recurrences at 3 months (1 against 6).^[8] Catgut embedding is not standard acupuncture, and neither trial used a sham control, so a placebo effect cannot be ruled out.

Symptom-level evidence comes from constipation. A meta-analysis of 6 trials with 1,457 people found that electroacupuncture produced more complete spontaneous bowel movements per week than sham electroacupuncture in chronic severe functional constipation, with no serious adverse events, although the effect faded after treatment ended and trial methods varied.^[9] A network meta-analysis of 45 trials of functional constipation found electroacupuncture had the lowest rate of adverse effects among the treatments compared.^[10] These findings concern constipation, not fissure healing.

How acupuncture may work

No mechanism studies specific to anal fissure turned up in PubMed. In Chinese medicine, points such as those near the sacrum and tailbone are chosen to relieve pain and regulate bowel function, as in the surgical trial above.^[7] How acupuncture might affect a fissure biologically is unknown.

What treatment involves

Treatment uses fine, sterile, single-use needles, usually left in place for about 20 to 40 minutes, with moxibustion (warming with burning mugwort) added when it suits the person. We reassess after a short course of visits. The postoperative trial gave acupuncture on each of the first 5 days after surgery.^[7]

Serious problems from acupuncture are rare. In prospective studies, about 9 in 100 patients had a minor reaction such as brief bleeding, soreness or redness at a needle site, and serious events occurred in about 1 in 10,000 patients.^[11] Tell the practitioner first if you have a bleeding disorder, take blood thinners, are pregnant, or have a pacemaker (relevant to electroacupuncture).

Ayurvedic medicine for Anal Fissure

The Ayurvedic view

Ayurveda describes a fissure-like condition called Parikartika, a word meaning cutting pain. Classical texts describe it as a complication of therapeutic purgation (Virechana) and of diarrhea.^[12] In this traditional framework, dry, hard stools and aggravated Vata are linked to the cutting pain. These are traditional categories, not biomedical diagnoses.

Therapies that may be used

Care is chosen for the individual and traditionally combines:

• Diet and daily routine to keep stools soft and regular, such as warm cooked meals, enough fluids and regular meal times
• Warm sitz baths, often followed by a medicated ghee or oil applied to the area; a ghee prepared with licorice (Yashtimadhu Ghrita) has been studied^[13]
• Herbal formulas such as triphala, traditionally used to support regular bowel movements, prescribed individually
• Transdermal medication therapy, in which an herbal preparation is applied to the skin

Ksharasutra, a medicated thread ligation, and anal stretching are procedures done by trained surgical practitioners and are not services we provide. Strong purgative Panchakarma therapy is not suited to a painful fissure, and Panchakarma in general is not appropriate during pregnancy, acute illness or frailty.^[12]

What the research shows

The research on Ayurveda for anal fissure is limited, and most of it concerns procedures we do not offer. A randomized trial of 36 patients with acute fissure compared licorice ghee with a lignocaine-nifedipine ointment for 4 weeks. Pain relief was slower with the ghee, ulcer healing was earlier, and the authors judged both similarly effective for symptom relief. It was small and had no placebo group.^[13]

Other Ayurvedic studies tested Ksharasutra. A trial of 100 patients with chronic fissure found better results when thread ligation followed anal stretching than with thread ligation alone.^[12] A trial of 30 patients found that both approaches gave significant results, with sphincterotomy giving relief somewhat sooner, though the difference between groups was not statistically significant.^[14] A clinical report of 39 fissure patients described mostly good relief, but it had no comparison group.^[15] No placebo-controlled trials were found.

Herbal medicine for Anal Fissure

Herbs and formulas that have been studied

Herbal research on anal fissure is sparse. The Cochrane review of non-surgical therapy listed clove oil and a "healer cream" among agents that looked promising in single studies without comparison to established medicines.^[5] A multicenter study of 157 patients tested an ointment made from a peptide extract of okra seeds (Hibiscus esculentus).^[16] Licorice-based ghee, mentioned above, is the Ayurvedic preparation with a randomized trial.^[13] No trials of Chinese herbal formulas for anal fissure turned up in PubMed.

What the research shows

The evidence is very limited. In the okra-peptide study, 65.5% of patients had complete healing at 30 days and pain scores fell, but all patients received the ointment and there was no control group.^[16] The Cochrane authors judged the clove oil and healer cream results as lacking comparison with established medications.^[5]

Herbs have not been shown to match the established ointments or surgery for chronic fissure. Warm sitz baths in plain water are a conventional measure: a systematic review of 11 articles found conflicting evidence on pain but overall support for their pain-relieving effect, and a randomized trial of 58 people found better satisfaction but no significant difference in pain or healing, with a perianal rash in two people.^{[17, 18]}

Safety and herb-drug interactions

Herbs are active substances and can interact with medicines. Reported interactions include extra bleeding when danshen or ginkgo is combined with warfarin and altered levels of several prescribed drugs with St John's wort.^[19] Tell us about every medicine you take, including ointments from your doctor.

In one study, about one fifth of Ayurvedic products bought online contained detectable lead, mercury or arsenic.^[20] Herbs should come from tested sources and be prescribed individually. Preparations applied to the skin can irritate it, and herbal laxatives can cause cramping or loose stools, so tell us before using either. Tell us if you are pregnant or breastfeeding or have liver or kidney disease.

Translating traditional medicine into modern biological language

The links drawn here are interpretation, not equivalence. Chinese medicine may describe an anal fissure as damp-heat or dryness in the intestines with blocked flow of qi and blood in the area. Researchers measure things that loosely parallel this picture: stool consistency, bowel movement frequency and tension in the anal sphincter.^{[1, 3, 9]}

Ayurveda's aggravated Vata, with dry hard stools and cutting pain, resembles the combination of constipation and sphincter spasm described in modern medicine.^{[3, 12]} No study has shown that a dosha or pattern corresponds to a specific biological process.

How this care fits with your medical care

Integrative care for anal fissure is complementary. Keep your physician, colorectal surgeon or gastroenterologist, and do not stop or change prescribed ointments or other medicines without your prescriber. We do not diagnose the cause of rectal bleeding or anal pain, and a fissure that does not heal needs medical assessment.^{[1, 2]}

Please bring your diagnosis, a full list of medicines and supplements, results of any colonoscopy or other tests, and details of any past anal or bowel surgery.

When to seek urgent medical care

Anal pain and bleeding have several causes, and some need prompt assessment.^[1]

• Heavy rectal bleeding, or bleeding with dizziness or fainting
• Fever, chills, or a swollen, hot or very tender area near the anus, which may signal an abscess
• A fissure that is off to the side, multiple, or not healed after several weeks
• Blood in the stool with unexplained weight loss, a change in bowel habits, or a family history of bowel cancer or Crohn disease
• Loss of bladder or bowel control

If any of these occur, see a physician promptly. For severe bleeding or any emergency, call 911 or go to the nearest emergency department.
