What Causes Urticaria (Hives)? Is It Dangerous? Natural Treatments to Avoid Complications Are you suffering from recurring hives, itching that keeps you awake at night, causing you to scratch until you bleed, and that allergy medication only provides temporary relief before the symptoms return? Many people call this condition "ghostly" because it appears and disappears suddenly: sometimes it's in one place, sometimes it's in another, it itches in the morning and disappears by afternoon, it itches at night and returns to normal during the day. In this video, Pharmacist Nguyen Quoc Tuan will help you understand the true nature of urticaria from both a modern medical perspective and a macrobiotic viewpoint, thereby providing natural, at-home treatment options to reduce reliance on medication and limit recurrence. 1) What is urticaria? Why does it itch so intensely? Urticaria (or hives) usually occurs when the body reacts to a "foreign agent" that the immune system perceives as potentially harmful. The body then releases histamine – a mediator that causes vasodilation, increases vascular permeability, and allows fluid to leak out of the capillaries, leading to edema, redness, and raised patches resembling mosquito bites. Video explains clearly: Why histamine causes itching but not pain Why scratching makes it itch worse (stimulating sensory nerves and releasing more histamine) Why "allergy" medications (antihistamines) can quickly relieve itching but often cause drowsiness and fatigue 2) Causes of hives: not just "allergies" Many people think hives are only caused by eating seafood, but in reality, they can stem from: Immune reactions to food (shrimp, crab, bee larvae, ant eggs, etc.), or a body's inability to metabolize certain types of protein Drug allergies (cold medicine, pain relievers/fever reducers, long-term antibiotics, aspirin, etc.) Environmental changes (cold ↔ hot, sunny ↔ rainy, air-conditioned room ↔ outside) And especially, hives can be a warning sign from within: Overloaded liver/toxin buildup (accompanied by fatigue) Fatigue, loss of appetite, dark urine, jaundice... Kidney dysfunction (lethargy, restless sleep, foamy urine, dull skin...) Dirty intestines/constipation causing toxins to "seep" back into the bloodstream, increasing inflammatory response – itching. 3) What is dermatographism? Why does it appear wherever you scratch? Some people experience dermatographism: just a light scratch, and after a few minutes, the skin will show raised lines along the scratch, even "drawing letters" on the hand. This is often related to overly sensitive mast cells in the skin, which easily release histamine due to friction, even without external allergens. 4) Is urticaria dangerous? When should you be cautious? Most cases of urticaria are benign and may resolve on their own after a few days. However, the video highlights two dangerous points: Severe allergic reaction/angioedema: deep swelling of the eyelids, lips, tongue, throat, etc., which can cause acute shortness of breath and a risk of anaphylaxis if not treated promptly. Warning about underlying conditions: fatty liver disease, liver disease, kidney disease, digestive disorders, etc. If only the itching is treated without addressing the root cause, the condition will easily recur and internal organs may worsen. 5) Natural Treatment: Reducing External Itching + Addressing the Internal Cause The video divides solutions into two approaches: Reducing External Skin Symptoms at Home Bathing/washing with betel leaves (warming, antibacterial, anti-inflammatory, reduces itching) Replacing with starfruit leaves, green tea, or perilla leaves (cooling, antibacterial) Bathing in rice bran water (rich in B vitamins, soothes the skin) Alternating between warm soaking and cold compresses to reduce irritation Applying a mixture of ginger juice and sesame oil (1:1) to warm, reduce itching, and protect the skin Applying crushed brown rice (mung beans can be added) to absorb toxins and reduce swelling and inflammation Addressing the Internal Cause (Nutritional Therapy – Lifestyle) Main focus: reduce food intake to give organs time to "clean up," reducing the burden on the liver, kidneys, and intestines Limit "negative"/easily irritating food groups: sugar, dairy, sweets, sweet fruits, etc. Avoid butter/cheese and industrial oils, and reduce alcohol consumption. Increase physical activity to sweat, aiding in detoxification through the skin. If suspected liver/kidney/intestinal issues: adjust accordingly (support liver function, treat constipation, increase regular exercise). If you are experiencing persistent or recurring hives, watch the entire video to understand the histamine mechanism, recognize warning signs related to liver, kidney, and intestinal issues, and apply natural remedies at home.
