Frankincense (Boswellia spp.)
Botany, Geographical Distribution, and Horticultural Information of Frankincense (Boswellia spp.)
Botany:
Frankincense, derived from the Boswellia species, comprises trees and shrubs known for their aromatic resin. The Boswellia genus belongs to the Burseraceae family. These trees are characterized by their papery bark, pinnate leaves, and clustered small white or pale pink flowers. The most notable feature of Boswellia trees is their ability to produce a fragrant resin, which is harvested as frankincense.
Geographical Distribution:
Boswellia species are native to arid regions of the Arabian Peninsula (Oman, Yemen), and northeastern Africa (Somalia, Ethiopia). They are also found in parts of India. These trees thrive in dry, mountainous regions and are often found growing on rocky outcrops and ravines.
Horticultural Information:
1. Cultivation: Boswellia trees are not widely cultivated and are mostly harvested from wild populations. They grow in harsh, arid environments and can tolerate poor, rocky soils.
2. Harvesting Frankincense: The resin is harvested by making incisions in the bark of the tree. The sap that oozes out hardens into frankincense, which is then scraped off the tree. This process is repeated several times a year.
3. Propagation: Boswellia trees are usually propagated from seeds. The germination rate can be low and seedlings require careful management due to their sensitivity to overwatering.
4. Uses of Frankincense: Frankincense has been used for thousands of years in religious rituals, traditional medicine, and perfumery. It is also used in modern aromatherapy and has potential anti-inflammatory properties.
5. Conservation Status: Some species of Boswellia are threatened due to overharvesting, habitat loss, and lack of successful natural regeneration. Conservation efforts are needed to ensure the sustainability of these valuable trees.

Frankincense- Phytochemistry<
The bioactive compounds in frankincense are responsible for its unique aroma, flavor, and purported health benefits.
Frankincense resin: The resin of frankincense is a complex mixture of organic compounds, including volatile oils, sesquiterpenes, and other triterpenoids. These compounds contribute to the resin’s aroma, flavor, and antioxidant properties.
Triterpenoids:
Triterpenoids are a group of organic compounds that are found in plants. They are responsible for the resin’s anti-inflammatory and antioxidant properties. Specific triterpinoids found in frankincense include the Boswellic acid group:
Boswellic acids:
Boswellic acids are a group of triterpenoids that are the main bioactive components of frankincense. They are responsible for the resin’s anti-inflammatory properties and have been shown to inhibit the production of leukotrienes, which are inflammatory molecules.
It is important to note that the relative proportions of boswellic acids in frankincense can vary depending on the species of Boswellia tree from which the resin is obtained. Additionally, the processing of the resin can also affect the content of boswellic acids. Therefore, it is important to choose high-quality frankincense products that are standardized for boswellic acid content.
Boswellic acids are a group of triterpenoids that are the main bioactive components of frankincense. They are responsible for the resin’s anti-inflammatory properties. The most abundant boswellic acids in frankincense are α-, β-, and γ-boswellic acids:
α-Boswellic acid: This is the most abundant boswellic acid in frankincense, making up about 50-60% of the total boswellic acid content. It has the strongest anti-inflammatory properties of all the boswellic acids.
β-Boswellic acid: This boswellic acid is less abundant than α-boswellic acid, making up about 20-30% of the total boswellic acid content. It has also been shown to have anti-inflammatory properties.
γ-Boswellic acid: This boswellic acid is the least abundant, making up about 10% of the total boswellic acid content. It has been shown to have anti-inflammatory and antioxidant properties.
Δ1-Trans-Lahadanonic acid (AKBA): This is a modified form of α-boswellic acid that has been shown to have stronger anti-inflammatory properties than α-boswellic acid.
3-O-Acetyl-11-keto-β-boswellic acid (AKBO): This is another modified form of β-boswellic acid that has been shown to have anti-inflammatory and antioxidant properties.
Δ5-Isopropylether-11-keto-β-boswellic acid (IB-KEA): This boswellic acid has been shown to have anti-inflammatory and antioxidant properties.
11-Keto-β-boswellic acid (KBA): This boswellic acid has been shown to have anti-inflammatory and antioxidant properties.
3-Hydroxy-11-keto-β-boswellic acid (HBK): This boswellic acid has been shown to have anti-inflammatory and antioxidant properties.
Δ6-Lahadanonic acid (LABA): This boswellic acid has been shown to have anti-inflammatory properties.
11-Epoxy-β-boswellic acid (EBE): This boswellic acid has been shown to have anti-inflammatory properties.
Isomeric forms of β-boswellic acid: Several isomeric forms of β-boswellic acid have been identified in frankincense. These isomeric forms have similar anti-inflammatory properties to β-boswellic acid.
Sesquiterpenes:
Sesquiterpenes are a group of organic compounds that are found in plants. They are responsible for the resin’s flavor and antioxidant properties:
α-Pinene: This sesquiterpene is the most abundant volatile compound in frankincense. It is responsible for the resin’s characteristic lemony aroma.
Limonene: This sesquiterpene is also a relatively abundant volatile compound in frankincense. It is responsible for the resin’s slightly sweet and citrusy aroma.
α-Thujene: This sesquiterpene is found in smaller amounts in frankincense. It is responsible for the resin’s slightly woody and spicy aroma.
(E)-β-ocimene: This sesquiterpene is found in very small amounts in frankincense. It is responsible for the resin’s slightly floral aroma.
β-pinene: This sesquiterpene is found in very small amounts in frankincense. It is responsible for the resin’s slightly woody and camphoraceous aroma.
Camphene: This sesquiterpene is found in small amounts in frankincense. It is responsible for the resin’s slightly sweet and citrusy aroma.
Ar-curcumene: This sesquiterpene is found in very small amounts in frankincense. It is responsible for the resin’s peppery aroma.
β-phellandrene: This sesquiterpene is found in small amounts in frankincense. It is responsible for the resin’s slightly woody aroma.
E-α-farnesene: This sesquiterpene is found in small amounts in frankincense. It is responsible for the resin’s slightly sweet and floral aroma.
β-bisabolene: This sesquiterpene is found in small amounts in frankincense. It is responsible for the resin’s slightly woody and earthy aroma.

Contraindications and Safety of Frankincense (Boswellia spp.)
Contraindications:
1. Pregnancy and Lactation: There is a lack of sufficient data on the safety of Boswellia during pregnancy and lactation. Due to its potential to increase menstrual flow, there is a concern that it might cause miscarriages. Therefore, it is generally advised that pregnant women avoid using Boswellia.
2. Autoimmune Diseases: Boswellia may stimulate the immune system and could potentially exacerbate symptoms in people with autoimmune diseases such as multiple sclerosis, lupus, and rheumatoid arthritis.
3. Bleeding Disorders: Boswellia might slow blood clotting and increase the risk of bleeding in people with bleeding disorders.
4. Surgery: Due to its potential effects on blood clotting, it is recommended to stop using Boswellia at least two weeks before a scheduled surgery to prevent excessive bleeding.
5. Medication Interactions: Boswellia may interact with medications that affect blood clotting, such as anticoagulants and antiplatelet drugs. It may also interact with anti-inflammatory medications and immune system modulators.
Safety:
1. General Use: Boswellia is likely safe when used in appropriate dosages. Most people do not experience significant side effects.
2. Side Effects: Some people may experience mild and transient gastrointestinal symptoms, including nausea, diarrhea, or constipation. Rarely, it may cause allergic reactions like skin rash or itching.
3. Dosage and Administration: The typical dosage of Boswellia extract ranges from 150 to 400 mg of boswellic acids taken three times daily. However, dosages can vary based on the specific condition being treated.
4. Long-term Use: Boswellia has been used safely in doses up to 1000 mg daily for up to 6 months. The safety of long-term use beyond six months is not well established.
