How Herbafama's Free AI Symptom Checker Works
Herbafama's symptom checker is powered by Llama 3.3 70B — one of the most capable open-source large language models available, with extensive medical training on clinical guidelines, diagnostic criteria, and evidence-based medicine from sources including the World Health Organization, American College of Emergency Physicians, and Mayo Clinic.
When you describe a symptom, the AI doesn't simply keyword-match against a database. It performs differential diagnosis generation — identifying the most likely conditions consistent with your specific combination of symptoms, duration, severity, and age, then assigning a triage level based on established clinical protocols.
What the AI Considers
🎯
Symptom Pattern
Location, quality (sharp/dull/burning), radiation, and associated symptoms are all analyzed together
⏱️
Timeline
Acute vs. chronic presentation dramatically changes the differential diagnosis and urgency level
📊
Severity Context
Your 1–10 severity rating combined with duration helps determine whether urgent care is warranted
🔗
Associated Symptoms
Even mild associated symptoms (nausea with chest pain, headache with neck stiffness) can signal dangerous conditions
👤
Age Context
The same symptom has very different clinical significance in a 25-year-old vs a 65-year-old
🚨
Red Flag Detection
High-risk symptom combinations are automatically elevated regardless of how the user frames the concern
Chest pain with radiation, stroke symptoms, difficulty breathing
How to Get the Most Accurate Results
The quality of AI symptom analysis depends directly on the quality of information you provide. Physicians are trained to ask specific questions to build a clinical picture — you can replicate this by including:
Location: Where exactly is the symptom? (right lower abdomen vs. left upper vs. central chest)
Character: What does it feel like? (sharp, dull, burning, pressure, stabbing, throbbing)
Radiation: Does it spread anywhere? (to the arm, jaw, back, groin)
Timing: Constant or intermittent? Getting better or worse?
Modifying factors: What makes it better or worse? (food, movement, position, time of day)
Associated symptoms: Even mild ones matter — nausea, fever, shortness of breath, dizziness
💡 Example of a poor description: "I feel sick." Example of a useful description: "Sharp pain 7/10 in my lower right abdomen, started 12 hours ago, worse with movement, accompanied by mild nausea and low-grade fever." The second description gives the AI everything needed to identify appendicitis as a top concern and recommend emergency care.
Limitations of AI Symptom Checkers
Understanding what AI symptom checkers cannot do is as important as knowing what they can:
Cannot physically examine you: Auscultation, palpation, percussion, and observation provide enormous diagnostic information unavailable to any text-based system
Cannot order diagnostic tests: Blood tests, imaging, cultures, and biopsies are often necessary for definitive diagnosis
Only knows what you tell it: Omitting relevant information (recent travel, new medications, family history) reduces accuracy
Cannot diagnose: It provides triage guidance and a differential list — diagnosis requires a licensed physician
When to Use the Symptom Checker vs. Calling 911
⚠️ Call 911 or go to the ER immediately for: Chest pain with radiation to arm or jaw · Thunderclap headache (worst headache of your life) · Sudden difficulty breathing at rest · Signs of stroke — FAST (Face drooping, Arm weakness, Speech difficulty, Time to call 911) · Coughing or vomiting blood · Unresponsiveness · Severe allergic reaction (throat swelling, can't breathe) · Suspected poisoning or overdose · Major trauma
Use the symptom checker for non-emergency concerns where you're trying to determine whether to schedule a doctor's appointment, try self-care, or seek same-day urgent care.

Herbafama's AI symptom checker is powered by Llama 3.3 70B — a large language model with extensive medical training. Studies of similar AI systems show accuracy of 65-75% for top-3 differential diagnosis. It is designed for triage (how urgent is this?) rather than definitive diagnosis, where it performs most reliably.
Yes. Every visitor gets 5 free AI symptom analyses before being prompted to create a free account. The AI health chatbot is completely unlimited and free for everyone. No credit card is ever required.
Yes. Enter your child's age in the symptom form for age-appropriate triage guidance. For children under 2 years or any child with severe symptoms, always contact a pediatrician directly rather than relying on any symptom checker.
Take that recommendation seriously. The AI is calibrated to flag high-risk symptom patterns conservatively. Call 911 or have someone drive you — do not drive yourself if you are experiencing chest pain, difficulty breathing, or neurological symptoms.
