Cleansing the Nasal Cavity: Nasal Irrigation Devices and Saline Solutions

For annoying nasal allergies, congestion, or sinusitis, "nasal irrigation" is a non-medical, effective physical treatment method. It can effectively remove allergens (such as dust mites, pollen, and polluted air), thick mucus, and enhance nasal cavity defenses to relieve congestion and symptoms of rhinitis.

Nasal Irrigation Devices and Saline Solutions

A Nasal Irrigator is a tool specifically designed to clean the nasal cavity. Its principle is to gently introduce a suitable mild liquid into one nostril, pass it through the nasal cavity, and then let it flow out from the other nostril or mouth, thus thoroughly removing dirt and secretions from the nasal cavity to achieve the effect of "nasal irrigation." The liquid used in the irrigator is not just ordinary water but a mild saline solution made from a special powder called "nasal saline."

Composition and Use of Nasal Saline

The core component is sodium chloride (salt), usually combined with sodium bicarbonate (baking soda). The role of baking soda is to buffer the pH of the solution, making it closer to the body's fluids, reducing stinging during washing, and helping clear thick secretions. To use, add the powder packet to boiled and cooled drinking water to a warm temperature (about 30∘C∼35∘C), stir until dissolved, and then use.

Why is it not recommended to use plain water or saline solution for nasal irrigation?

During nasal irrigation, the "concentration" and "composition" of the solution are key to determining comfort and safety.

Solution	For Nasal Irrigation	Core Reason/Advantage
Plain Water	Not Recommended	The salt concentration is too low, leading to osmotic pressure causing water to enter the nasal mucosa, resulting in severe stinging, a choking sensation, and damage.
Saline Solution	Not Optimal	While the concentration (0.9%) is close to body fluid levels, it is not as effective as nasal saline.
Nasal Saline	Best Choice	Main component sodium chloride, with added sodium bicarbonate (baking soda) to buffer pH, making it milder and less irritating than plain saline, aiding in clearing secretions.

:bulb: Key Points

• It is recommended to use both a "nasal irrigator" and "nasal saline" together.
• "Nasal saline" is specially formulated mild saline for nasal irrigation (with specific concentration and composition).
• When using "nasal saline," dissolve it in warm water before use.
• Reasons you shouldn't use plain water (low osmotic pressure, potential for stinging, choking sensation, damage to nasal mucosa).
• Although the saline solution has a concentration close to body fluids (0.9%), it lacks the benefits of nasal saline.
• Advantages of nasal saline (added sodium bicarbonate, more mild and comfortable, good buffering capacity, convenient and economical).

Recommendations for Nasal Irrigators and Saline from Japanese Drugstores

Japanese drugstores and online stores offer a variety of popular nasal care products, most of which are "nasal irrigators (with or without included nasal saline/solution)." Below are some major recommended brands and products:

• When there is excessive nasal secretion or severe congestion, you can choose the Kobayashi Thick Mucus series or HanacleanS for a larger capacity and more thorough rinse.

Quick Symptom Relief: Antihistamines and Steroid Medications

The Mechanisms and Choices between Antihistamines vs. Steroids

Antihistamines and steroids are common components in anti-allergy medications. To effectively treat allergy symptoms, it is important to understand the fundamental differences between these two types of drugs: one intercepts signals (emergency relief), while the other eliminates inflammation (deep control).

1. Antihistamines: Quick Relief for "Itching, Runny, Sneezing"

• Mechanism: Antihistamines work by blocking histamine. When allergens stimulate your body, cells release histamine (an allergy inflammation signal). Antihistamines act like they are blocking the signal exit, preventing the allergy alarm from spreading throughout the body, thus stopping symptoms immediately.

• Suitable Symptoms: They specifically address "acute signals" such as sneezing, runny nose, itching of the skin, and itchy eyes.

2. Steroid Medications: Deep Control for "Swelling, Redness, Pain"

• Mechanism: Steroids are powerful anti-inflammatory drugs. Their effect goes deeper by directly shutting down the entire inflammatory response production line.
• Suitable Symptoms: They are specifically used for "chronic inflammation," eliminating long-term or severe tissue swelling, redness, and pain. For symptoms already causing prolonged nasal congestion or eczema with redness and swelling, steroids are a more effective solution.

Allergic Medication Recommendations from Japanese Drugstores

This list compiles the best-selling anti-allergy products from Japanese drugstores. You can choose the most suitable product based on the "affected area" or "type of medication" (antihistamine/steroid):

💡 Antihistamine/Steroid Medication Purchase Advice:

• For mild, acute itching or runny nose, choose antihistamines. For long-term issues or significant swelling and persistent redness, choose steroids.
• Oral steroids cannot be purchased at Japanese drugstores! If needed, please consult a doctor.
• Steroid ointments vary in strength; when purchasing, be sure to consult with a pharmacist at the drugstore to ensure the strength is appropriate for your affected area and symptoms.

Fundamental Adjustment: Probiotics for Improving Allergic Constitution

To improve allergic constitution with the help of probiotics, the key is to select products containing "active probiotics."

Thus, we focus our recommendations on Myolis Powder, Shinbeyo Bizyme S, and Wakogen Gastrointestinal Tablets, which contain active bacteria. Popular product EBIOS Tablet is not recommended as its main ingredient is brewer's yeast, which does not contain active probiotics. These active bacteria indirectly stabilize the overall immune system by balancing intestinal flora, particularly alleviating nasal allergy symptoms.

Japanese Drugstore: Recommended Probiotics for Allergies

Popular Japanese intestinal medicines have different focuses in terms of form and efficacy. Below are recommended Japanese pharmaceutical-grade probiotics for improving allergic constitutions:

Image	Product Name	Main Ingredients and Type	"Core Benefits" for Physical Conditioning
	Miyarisan	Single Strain Butyric Acid Bacteria. Pharmaceutical (Intestinal Medicine)	Strengthens Barrier Anti-allergy: Butyric acid bacteria specifically repair the intestinal mucosal barrier, which is key to preventing allergens from entering the body.
	Shinbeyo Bizyme S	Three Active Probiotics (Lactobacillus, Bifidobacterium). Designated Quasi-drug	Long-term Stable Maintenance: Gently establishes whole intestinal flora balance, suitable for long-term use to gradually adjust the constitution.
	Wakogen Gastrointestinal Tablets	Active Probiotics + Digestive Enzymes + Brewer's Yeast. Designated Quasi-drug	Comprehensive Repair and Nutrition: Probiotics for intestinal health, enzymes aid digestion, supporting anti-allergy from an overall health perspective.

💡 Probiotic Purchase Advice for Allergy Relief:

When selecting probiotics to aid in allergy management, focus on whether the product can effectively establish an intestinal barrier and regulate immune responses:

• [Strengthen Barrier, Combat Allergens]: Miyarisan is the top choice. Its butyric acid bacteria focus on repairing intestinal cells, making it an ideal option for fundamentally addressing allergic constitution.

• [Digestive Aid, Reduce Burden]: If you have issues with bloating or indigestion, choose Wakogen Gastrointestinal Tablets. They help break down food through enzymes, lighten the gastrointestinal load, improve overall health, and support immune stability.

• [Gentle Stability, Long-term Care]: Choose Shinbeyo Bizyme S. It's suitable for families seeking gentle, long-term maintenance of a stable microbiome environment.
