Every year, millions of people worldwide are bitten by snakes, and thousands lose their lives due to delayed or incorrect treatment. While folk remedies such as using lemon seeds to “draw out the venom” have circulated for generations, medical experts warn that no home remedy can replace proper medical care.

That said, some traditional practices — when used as first aid while waiting for emergency help — may help limit further damage. Understanding how to act within the first minutes after a snake bite can literally save a life.

⚕️ What Happens When a Snake Bites

Snake venom contains complex toxins that attack the blood, nerves, and tissues. Depending on the species, symptoms may appear within minutes, including swelling, pain, paralysis, or difficulty breathing.

According to the World Health Organization (WHO, 2023), victims should always be transported to a medical facility as quickly as possible, as antivenom is the only proven treatment for serious snakebites.

🚨 Step-by-Step: What to Do Immediately After a Snake Bite

1️⃣ Stay calm and keep the victim still

• Panic increases heart rate and spreads venom faster.

• Reassure the person and immobilize the bitten limb.

2️⃣ Remove tight items

• Take off rings, watches, or bracelets near the bite to prevent restriction as swelling begins.

3️⃣ Apply a pressure immobilization bandage (for cobra or viper bites)

• Use a firm elastic bandage, wrapping from fingers/toes upward.

• The bandage should be snug but not cut off circulation — you should still feel a pulse.

• Splint the limb to minimize movement.

⚠️ Do not use this method for green pit viper (rắn lục) bites, as pressure can worsen local tissue damage.

4️⃣ Clean the wound gently

• Rinse with mild soapy water or saline.

• Avoid cutting, sucking, or applying chemicals to the bite — these do not remove venom and may cause infection.

5️⃣ If breathing stops

• Begin CPR or mouth-to-mouth resuscitation while waiting for medical help.

6️⃣ Transport safely

• Keep the victim lying down.

• Ensure the bitten limb remains below heart level to slow venom spread.

• Call emergency services immediately (in Vietnam: 115).

CDC (Centers for Disease Control and Prevention, 2022) emphasizes: “Do not delay hospital transport for any home remedy. Antivenom must be administered by trained healthcare providers.”

🍋 The “Lemon Seed Remedy” — Folk Wisdom Explained

In some rural traditions, lemon seeds (hạt chanh) are believed to contain natural enzymes that “draw out toxins.” The folk method involves chewing or crushing 15–20 fresh lemon seeds, swallowing the juice, and applying the pulp to the bite site.

However, no scientific evidence supports this method as an antidote.
At best, it might provide a cooling or astringent sensation on the skin — but it cannot neutralize venom or prevent systemic poisoning.

Vietnam’s National Institute of Malariology and Parasitology (2021) warns that relying on herbal or seed-based treatments can lead to delayed hospital care and worsen outcomes.

If you choose to use lemon seeds while waiting for help, treat it only as a temporary comfort measure, not a cure. Always proceed to a hospital immediately.

🧴 Safe Supportive Remedies While Awaiting Help

If you are far from medical facilities:

• Keep the wound clean and covered.

• Hydrate the victim if conscious.

• Use a cold, clean compress to reduce swelling (avoid applying ice directly).

• Avoid alcohol or herbal concoctions that could affect blood flow.

⚠️ Common Myths to Avoid

❌ Do not cut or suck the wound – this does not remove venom.
❌ Do not apply tourniquets – they can cause tissue necrosis.
❌ Do not apply herbs or chemicals directly to the bite.
❌ Do not try to capture or kill the snake – take a photo if safe, for identification.

🧬 The Real Lifesaver: Antivenom

Antivenom is the only scientifically proven therapy to neutralize venom toxins. It must be administered intravenously under medical supervision.

The Lancet (2023) reports that timely antivenom administration within 1–2 hours after a bite can reduce mortality by over 80%.

🩺 Key Takeaway

Lemon seeds, garlic, or herbal poultices cannot replace emergency care.
The correct approach after a snake bite is:

CALM – CLEAN – COMPRESS – CALL – CARE

As WHO emphasizes:
“Traditional remedies may provide comfort, but antivenom saves lives.”
