- Efficiency: 98-100% bioavailability
- Price: Similar to chips
- Storage: Can be stored for 5-10 years (aroma may change due to oxidation)
3.2 Component Content and Quality
The quality of Agarwood is determined by the content of Agarospirol and Jinkohol.
| Grade | Agarospirol | Jinkohol | Quality | Use |
|---|---|---|---|---|
| Kynam | 70-75% | 15-20% | ⭐⭐⭐⭐⭐ (Exceptional) | Collection, meditation |
| Grade A | 60-65% | 12-18% | ⭐⭐⭐⭐ (Superior) | Everyday aroma appreciation |
| Grade B | 50-55% | 10-15% | ⭐⭐⭐ (Medium) | Beginner use |
3.3 Storage and Freshness
Agarwood can be stored for a long time, but its quality changes depending on the storage method.
- Optimal Environment: Room temperature (20-25℃), humidity 40-60%, no direct sunlight
- Container: Vacuum-sealed container (to prevent oxidation)
- Shelf Life: Chips can last 10-20 years, powder can last 5-10 years
- Benefits of Aged Agarwood: Aroma deepens and becomes more complex (like wine)
- Freshness Check: Is the aroma refreshing and intense? Is there no moldy smell?
4. Agarwood Sticks and Incense Burners
4.1 Types of Sticks
Agarwood sticks are divided into two main types.
📌 Direct Incense Stick
- Agarwood wrapped around a bamboo stick
- Used by lighting one end
- Burns in a flame state, resulting in significant aroma loss
- Bioavailability: 45-55%
- Price: Affordable
- Advantages: Convenient for use at work or home
- Disadvantages: Low efficiency and high chemical component loss
📌 Half-Incense Stick
- Agarwood mixed with chemical additives
- Partially attached to bamboo
- Additives burn before Agarwood components during combustion
- Bioavailability: 20-30%
- Price: Very affordable
- Advantages: The cheapest and lasts the longest
- Disadvantages: Agarwood content is below 50%, artificial fragrance
4.2 Mechanism of Chemical Component Loss
This scientifically explains why the efficiency of sticks is low.
[Raw Material: 100% Agarwood Components] ⬇️ (Ignition) [Step 1: Temperature Rise (200-300℃)] └─ 15% Evaporation loss of Agarospirol └─ 20% Evaporation loss of Jinkohol[Step 2: Active Combustion (400-600℃)] └─ Remaining 45% Agarospirol oxidatively decomposed └─ 65% Jinkohol oxidatively decomposed └─ 10-15% loss due to incomplete combustion
[Step 3: Aroma Dispersion] └─ 50% loss during dispersion in the air
[Final Absorbed Components] └─ Only about 15-20% of the original components produce actual effects
4.3 Convenience of Use vs Efficiency
Understand the trade-off between convenience and efficiency.
| Criteria | Chips | Direct Sticks | Essential Oils |
|---|---|---|---|
| Ease of Use | ⭐⭐ (Requires incense burner) | ⭐⭐⭐⭐ (Ready to use) | ⭐⭐⭐ (Requires diffuser) |
| Efficiency | ⭐⭐⭐⭐⭐ (100%) | ⭐⭐ (55%) | ⭐⭐⭐⭐⭐ (85%) |
| Cost Efficiency | ⭐⭐⭐ (High) | ⭐⭐⭐⭐ (Cheapest) | ⭐⭐ (Most expensive) |
| Fragrance Intensity | ⭐⭐⭐⭐ (Strong) | ⭐⭐⭐ (Medium) | ⭐⭐⭐⭐⭐ (Very strong) |
5. Agarwood Scented Candles and Moisturizing Diffusers
5.1 Composition of Scented Candles
Agarwood scented candles minimize the components of agarwood while emphasizing fragrance.
🕯️ General Composition of Agarwood Scented Candles
- Agarwood Component: 30~40% (Actual agarwood chips/powder)
- Wax (Beeswax/Paraffin): 50~60% (Burns to disperse fragrance)
- Fragrance Oil: 5~10% (Artificial fragrance added)
- Additives: 1~5% (Colorants, stabilizers, etc.)
Issue: The majority of the agarwood components included in agarwood scented candles are used for visual effects rather than fragrance, resulting in very limited health benefits.
5.2 Duration and Fragrance Intensity
Here is a comparison of the performance of scented candles.
| Type of Candle | Agarwood Content | Duration | Fragrance Intensity | Bioavailability | Price |
|---|---|---|---|---|---|
| Regular Candle | 0% | 4-6 hours | Medium-Strong | 0% | $ (Inexpensive) |
| Agarwood Mixed Candle | 30~40% | 5-7 hours | Medium | 10~15% | $ (Moderate) |
| Agarwood Dominant Candle | 60~70% | 6-8 hours | Weak | 20~25% | $$ (High) |
5.3 Impact on Indoor Air Quality
Here are the advantages and precautions of scented candles.
- Advantages: Soft fragrance, visual beauty, low price
- Precautions: Fine dust generated from wax combustion (deterioration of indoor air quality)
- Health Effects: Very limited (primarily reliant on fragrance)
- Recommendations: Use for a short time (1-2 hours), essential to ventilate
6. Agarwood Essential Oils and Extracts
6.1 Refinement Process of Essential Oils
Agarwood essential oil is a concentrated form obtained through high-temperature distillation.
[Step 1: Prepare Agarwood Chips] └─ Select only high-quality agarwood[Step 2: High-Temperature Distillation (150~200℃)] └─ Steam passes through agarwood chips └─ Extract volatile components
[Step 3: Cooling and Separation] └─ Separate oil layer and water layer └─ Extract only the oil
[Step 4: Refinement] └─ Remove impurities └─ Final concentration of 80~90%
[Final Yield] └─ 1kg of chips → 1020ml of oil (12%) └─ High price due to very low yield
6.2 Bioavailability and Absorption Pathways
There are various ways for essential oils to be absorbed.
🌬️ Three Main Absorption Pathways
- Inhalation: Inhaled through a diffuser → Olfactory nerve → Limbic system in the brain (emotion, memory center)
- Dermal Absorption: Applied to the skin with massage oil → Enters bloodstream (muscle pain, skin health)
- Oral Intake: Taken in capsules → Digestive system → Liver metabolism → Bloodstream (highest bioavailability 85%)
6.3 Risks and Benefits of High Concentration
Essential oils are powerful, so caution is necessary.
| Aspect | Benefits | Precautions |
|---|---|---|
| Effect | Extremely fast and powerful effect (within 5-10 minutes) | Possible adverse effects from overuse |
| Dose | Only a small amount is sufficient (1-3 drops) | Accurate dosage measurement is essential |
| Storage | Can be stored for a long time (1-3 years if refrigerated) | Sensitive to light and heat |
| Safety | Natural extract | Avoid during pregnancy, with infants, and pets |
7. Frequently Asked Questions (FAQ)
Q1. What is the most effective product?
A: It depends on the purpose. Maximizing health benefits: Essential oil or capsules / Balancing fragrance enjoyment and efficiency: Agarwood chips / Focusing on convenience: Direct sticks

Q3. Which is better, sticks or chips?
A: Efficiency is superior with chips (100%), but convenience is better with sticks. If you have time, I recommend chips; if you're busy, go for sticks.
Q4. Are essential oils really safe?
A: Pure agarwood essential oil is safe, but direct ingestion requires guidance from a professional. Using a diffuser or diluting it is safe.
8. Conclusion: Principles for Product Selection
The perfect Agarwood product lies in a choice tailored to its purpose and situation.
Three principles of selection:
- If the purpose is clear: Health → Oil/Capsules, Scent appreciation → Chips, Convenience → Sticks
- If the budget is limited: Start with sticks, and if sufficient, upgrade to chips or oil
- If quality is the top priority: Agarwood chips > Powder > Direct sticks > Scented candles in order of recommendation
The form of the product determines half of its effectiveness. Even with the same Agarwood, chips and scented candles provide completely different experiences.
