In the aromatic landscapes of Madagascar, a unique product takes center stage: clove leaf oil (CLO). Extracted from the dried leaves of the clove tree (Syzygium aromaticum), CLO is a remarkable essential oil with vast industrial and commercial applications. The oil extracted solely from clove leaves does not necessarily contain 80-82% eugenol (i.e. the global standard for CLO export). Thus, clove oil is also derived in smaller quantities from clove stems and buds but the primary source remains the dried leaves. These various extracts are homogenized to standardize the oil’s eugenol concentration at 80-82%, forming the base for further refinement.
What makes the story quite interesting is the before and after, the progression, how basic low quality leaves that contained about 80-82% eugenol got transformed to a highly processed 99% eugenol in Europe and Asia’s factories. It is basically how chemistry and agriculture fused at a perfect instant. Here, the point is, 1% purity is huge and can make millions in the market.
Chemical Composition of Clove Leaf Oil
Clove leaf oil is primarily composed of:
- Eugenol (80-82%)
- β-Caryophyllene (15-20%)
- Eugenyl acetate (0.3-0.7%)
- α-Humulene (1.5-2%)
- Other minor components (1-2%)
Madagascar’s Clove Oil Industry: From Farm to Ultra-Pure Eugenol
Madagascar is one of the world’s largest exporters of clove leaf oil. Local farmers and processors use a simple steam distillation procedure to produce oil that contains 80-82% eugenol. The extraction is mostly done in small distilleries that are scattered across clove growing regions. This extracted oil is then supplied to the local companies by the collectors and is further exported to international market. Village collectors play a pivotal role in the supply chain of CLO in Madagascar. They pre-finance distilleries by providing monetary advances or essential household goods, ensuring that farmers and small-scale processors can continue their work. In return, the distilled CLO is sold exclusively to these collectors, who then supply regional buyers. Regional collectors aggregate oil from hundreds of village collectors, creating an efficient, albeit decentralized, supply chain. Every year, Madagascar sends approximately 1,800-2,000 tons of this oil to other nations. Companies acquire this 80-82% concentrated oil because it is less expensive to ship and refine at their own facilities. When this oil reaches processing facilities, it is refined numerous times to enhance the eugenol level to 99%. This ultra-pure eugenol is used in making pharmaceuticals, high-end perfumes, and other specialized items.
Industrial Applications of Clove Leaf Oil
1. Pharmaceutical & Medical Applications
1.1 Dental Care
Due to the anesthetic properties of clove leaf oil, Eugenol is employed in dental procedures. In procedures like temporary fillings and root canals, eugenol is efficacious because it has a weak numbing and antibacterial effect. Eugenol’s analgesic properties make it a key component of clove leaf oil, which is widely recognized as a natural remedy for pain relief and gum inflammation. It has antiseptic characteristics which led to its usual inclusion in mouthwash and toothpaste for the prevention of gingivitis. Eugenol is also frequently included in numerous over-the-counter medicines because it has a numbing effect.
1.2 Pain Relief Products
Due to eugenol’s natural properties, clove leaf oil was made a pain reliever. Clove leaf oil has been used in various forms of ointments and balms that relieve muscle pain and joint stiffness by providing warmth to the area, which is ideal for arthritis patients as it soothes the muscles that are tense. Additionally, it can be used as a pain reliever for migraines and headaches as it has anti-inflammatory properties. Many aromatherapy products contain this oil that help in alleviating headaches as it has penetrating heat and is comforting when applied on the temples or inhaled.

Clove oil is often used in low concentrations to prevent bacterial growth in pickles, sauces, and dried foods, where it helps maintain product quality and freshness.
4. Pesticide Industry
Clove leaf oil plays a significant role in the pesticide industry due to its insecticidal and repellent properties, primarily from its eugenol content. It is used in agriculture to control pests in stored grains and crops, acting as a natural fumigant and reducing infestations without harmful residues. Its antifungal properties also help prevent mold growth. In domestic settings, clove oil is a key ingredient in natural insect repellents and sprays, effectively deterring pests like mosquitoes, ants, and cockroaches while offering an eco-friendly and biodegradable alternative to synthetic pesticides.
Conclusion
Clove leaf oil exemplifies nature’s remarkable contribution to modern industry. From its origins in Madagascar’s plantations as 80-82% eugenol oil to its transformation into 99% pure eugenol. It plays an essential role in the production of personal care products, pharmaceuticals, and food items, among others. The oil’s general antimicrobial, analgesic, and aromatic properties make it one of the most significant components in various products including dental care and high-end perfume. Such industries are increasingly seeking green alternatives, thus clove leaf oil is a true ambassador of natural wisdom and modern technology, proving that some of our most effective industrial ingredients come straight from nature.
