Camphor

Camphor, “Karaboon” in Thai (การบูร), is an essential component of traditional Thai medicine.

It comes from the leaves, branches and wood of the Camphor tree. Energizing and tonic, it is known to relieve pain, respiratory conditions, improve blood circulation and reduce inflammation.

We prefer camphor produced in a traditional way in the regions of Surat Thani, Petchabun and Ranong, renowned for the excellence of their production.

Benefits and Uses

Camphor is known for its multiple benefits essential to traditional medicine and cosmetics.

Analgesic

Helps to relieve muscle, tendon and joint pain, in particular by improving blood circulation in the affected area. Helps relieve headaches and migraines

Anti-inflammatory

Helps to reduce body inflammation, swelling and stiffness. Relieves muscle, joint and ligament pain. Helps to reduce the symptoms of certain inflammatory conditions such as arthritis, rheumatism, sprains, but also asthma and bronchitis.

Expectorant

Helps to relieve nasal congestion and to clear the airways, for example in cases of cough, cold and sinusitis.

Antispasmodic

Reduces muscle spasms, relieves tension and promotes relaxation.

sedative

Intervenes in the regulation of levels of cortisol, the stress hormone. It thus has a calming effect on the mind and helps to reduce stress and anxiety.

refreshing

Provides a feeling of freshness and soothing when applied to the skin. Used in particular to soothe sunburns and light burns.

Repellent

Its penetrating odor acts as a natural repellent against insects such as mosquitoes, flies, and moths.

Historical Origins

Camphor is an integral part of traditional medicine in different cultures around the world. Its use dates back to ancient times and it has been widely used in Asia, especially in India, China, Japan, Korea, Thailand, and Vietnam.

In Thailand, camphor has been used since the origins of traditional medicine, in various therapeutic practices. It is known under the name “Karaboon” and is mentioned in all the traditional medical literature. It can thus be found in the oldest works such as “Tamra Maekhong” (ธรรมราชแม่โขง), also known as the “Royal Treaty of the Mae Khong River”, an ancient manuscript written during the Sukhothai dynasty period, which lasted from the 13th to 14th centuries. But also more modern ones such as the “Tamra Ya Mongkol”, also known as “Queen Sirikit's Medical Treatise”, compiled during the reign of King Rama IV (19th century)

In China, camphor is mentioned in the “Shennong Ben Cao Jing” (Yellow Emperor's Classic of Medical Matters), a medical text dating from around 200 BC.

In India, it is mentioned in ancient texts such as the “Charaka Samhita” and the “Sushruta Samhita” which date back to several centuries before our era.

In Japan, he appears in major books such as the “Ishinpō” (医心方) by Tametsugu Shōnen, written in the 14th century and the “Yōjōkun” (養生訓) by Kaibara Ekiken written in the 17th century

The use of camphor has also spread to other regions of the world, especially in Europe and America, where it has been incorporated into a number of medicinal preparations.

Today, camphor continues to be used extensively in a variety of medicinal, pharmaceutical, and cosmetic applications.

SOURCES

In Thailand, camphor is mainly extracted from two tree species that are commonly grown commercially:

  • Cinnamomum camphora: Also known as camphor, this tree is native to China. The leaves, branches and wood of this tree are used to extract its essential oil, which is particularly rich in camphor.
  • Dryobalanops aromatica: Also called “eagle wood”, this species is found in the tropical forests of Southeast Asia. The essential oil extracted from the bark of the tree is also rich in camphor.

In addition to these two tree species, other plants rich in camphor are present in Thailand, such as Artemisia vulgaris, a herbaceous perennial that grows in mountainous regions of Thailand. However, commercial camphor production in Thailand is mainly based on the two tree species mentioned above.


Thailand is one of the world's main producers of camphor, with several regions of the country renowned for high-quality production:

  • Surat Thani Province: Located in southern Thailand, it is home to a large quantity of camphor trees, mainly in the districts of Phanom, Ban Na San and Tha Chana.
  • Phetchabun Province: Located in northern Thailand, it has a solid reputation and is home to large camphor farms in the districts of Khao Kho and Lom Sak.
  • Ranong Province: Located on the border between Thailand and Myanmar, it is particularly recognized for its production of high quality camphor.

We favor our camphor supplies from these regions, which benefit from a favorable climate and provide top quality camphor, mainly produced on traditional farms.

PRODUCTION

In Thailand, the production of camphor crystals generally follows the following steps:

  • Resin harvesting: Incisions are made on the tree trunk, which allows the resin to flow out. It is collected in special containers that are placed at the foot of the tree.
  • Initial cleaning: The resin is then cleaned to remove impurities such as pieces of bark or wood. This is done by filtering the resin through a sieve or by letting the resin sit for a long time for impurities to settle in the bottom.
  • Distillation: The cleaned resin is then heated, traditionally in copper stills. The resin volatilizes and is transformed into vapor.
  • Condensation: The resin vapor then passes through a cooling system where it condenses to form solid camphor crystals.
  • Purification: The camphor crystals obtained are subjected to an additional purification step by filtration to remove the remaining impurities.
  • Drying and packaging: the camphor crystals are then dried in air or in controlled dryers to remove any trace of humidity. Once dry, they are packaged in appropriate containers, ready to be used or marketed.

COMPOSITION

Camphor is an organic compound from the terpene family and comes in the form of a white solid that is translucent and smooth to the touch. A strong and fresh smell as well as a bitter and very strong flavor make it special.

Camphor compounds include:

  • Camphene: An isomer of camphor, which has an almost similar molecular structure.
  • Borneol: Terpene alcohol that is often found in essential oils.
  • Isoborneol: Borneol stereoisomer.
  • Pinene: Another terpene commonly found in essential oils.
  • Sabinene: Monocyclic terpene found in plant essential oils.
