- Very peculiar sensation: “Something hard, like a lump or egg, stuck at the pit of the stomach”
- Pain and distress immediately after eating
- Marked gastric fullness and pressure
- Constipation with weak digestion
- No appetite in the morning, but hunger or craving later (noon/night)
- Sleeplessness from hunger

- Inflammatory, stitching pains worse from motion → consider Bryonia

4) Uses in Homeopathy
- A. Common Ailments:
- Indigestion, functional dyspepsia: heaviness/fullness after eating, sour belching, heartburn, lump sensation.
- GERD-like symptoms, especially with the “egg/lump” keynote.
- Dyspepsia linked to excess tea or tobacco.
- B. Chronic Patterns:
- Chronic dyspepsia in the elderly or sedentary, with constipation and post-meal discomfort.
- Functional heart symptoms (palpitations from gastric issues)—always medically exclude cardiac disease.
- C. Extreme/High-Risk Situations:
- Case reports mention severe reflux, Barrett’s esophagus, and even rectal bleeding/cancer—these require specialist medical care, not self-treatment.
5) Constitutional Portrait (Homeopathic Type Most Affected)
- Typically described for older individuals with sluggish digestion.
- Symptoms worsened by overeating, tea, or tobacco.
- Classic pattern: lack of appetite in the morning, with increased craving later in the day.
6) Potency and Practical Usage
- Mother Tincture (Q/Ø): Used for pronounced gastric atony and sluggishness—local, functional cases.
- Low Potencies (6C/6X/12C): For mainly physical symptoms and repeated dosing.
- 30C: Common for cases with clear keynote symptoms.
- 200C and Higher: Reserved for distinct constitutional patterns—clinician supervision advised.
7) Effects/Considerations in Kids and Seniors
- Kids:
- Used mainly for digestive distress patterns in homeopathic texts.
- Persistent or severe symptoms (vomiting, dehydration, pain, blood in stool, etc.) require prompt medical attention.
- Seniors:
- Frequently cited for “dyspepsia of the aged.”
- High vigilance for medication interactions, GI bleeding, and cardiac risk; red-flag screening is essential.
8) Documented Clinical Applications (with References)
- Case Report (Functional Dyspepsia): Abies nigra included among remedies for a case with epigastric pain after oily foods, early satiety, heaviness, and heartburn.
- Barrett’s Esophagus Case: Published paper discusses Abies nigra 30 in a Barrett’s esophagus setting—again, specialist care required.
9) Key Repertory Rubrics (High-Yield for Selection)
- Stomach: Sensation of a lump/hard-boiled egg at cardiac end/lower esophagus
- Stomach: Pain after eating
- Stomach: Dyspepsia in aged persons
- Stomach: Heartburn, sour eructations, reflux (with keynote)
