The Cannabaceae family is a group of plants in the order Rosales, consisting of approximately 11 genera and around 170 species. This family includes some economically and culturally significant species, such as hemp (Cannabis sativa) and the nettle (Urtica). The plants in this family are found in temperate and subtropical environments, and they are known for their industrial, medicinal, and nutritional properties.

General Description

Plants in the Cannabaceae family share several common characteristics:

• Leaves: The leaves are usually simple, alternate, and entire, with serrated or lobed margins. They are often aromatic when crushed and may have a leathery texture. The plants are generally evergreen.
• Flowers: The flowers of Cannabaceae species are usually unisexual, and many species are dioecious, meaning male and female flowers grow on separate plants. The flowers are typically small and inconspicuous, often yellow or green, and are wind-pollinated.
• Fruits: The fruits are typically capsules or drupes, and the plants produce seeds that are rich in oils and nutrients. In some species, the seeds are used for food or industrial purposes.
• Stems and Roots: Most species are herbaceous or shrub-like, with roots that can range from shallow to deep, depending on the species.

Chemical Composition

Plants in the Cannabaceae family, particularly Cannabis sativa, contain a variety of bioactive compounds with medicinal, culinary, and industrial applications:

• Cannabinoids: Cannabis sativa is the most well-known species in the family and contains a range of chemicals called cannabinoids, including tetrahydrocannabinol (THC) and cannabidiol (CBD). These compounds are known for their psychoactive and therapeutic properties, which is why hemp has historically been used for both medicinal and recreational purposes.
• Terpenes: The terpenes present in hemp and other family members contribute to their aroma and also have anti-inflammatory, analgesic, and antioxidant properties.
• Fatty Acids: The seeds of Cannabis sativa are rich in essential fatty acids, such as linoleic acid and alpha-linolenic acid, which are important for heart health and lipid balance.
• Proteins: Hemp seeds are a rich source of high-quality plant-based proteins, containing all the essential amino acids needed for human nutrition.
• Fiber: Hemp fiber is strong and is used for the production of textiles, ropes, paper, and building materials.

Physical Properties

The Cannabaceae family is characterized by the following physical traits:

• Leaves: The leaves are typically compound and can be wide, palmate, or narrow, as in the case of hemp. Cannabis sativa leaves are particularly well-known for their characteristic 5-7 lobed shape and are used in various industrial and medicinal sectors.
• Flowers: The flowers of the family are generally small and unisexual. Many species have flowers that are easily recognizable for their arrangement on separate male and female plants, as in Cannabis.
• Seeds: Hemp seeds are oval in shape, light brown or green in color, and contain oils and proteins that are used in food and cosmetics.
• Fiber: Hemp fiber is long, strong, and is used for various industrial products, including textiles, ropes, and biodegradable materials.

Production and Harvesting

Plants in the Cannabaceae family, particularly Cannabis sativa, are grown for multiple purposes:

• Hemp (Cannabis sativa): Hemp is grown mainly for its seeds, which are a source of oil, and for its fiber, which is used in the production of textiles, paper, and biodegradable materials. Hemp seeds are harvested for oil production and food use, while the fiber is collected for industrial purposes.
• Hemp Oil: Hemp oil is extracted from the seeds and used both in food products and cosmetics for its nutritional and moisturizing properties.
• Hemp Flowers: The flowers of Cannabis sativa are used for the production of cannabinoid extracts, such as CBD, which are used in alternative medicine for treating anxiety, chronic pain, and other conditions.

Applications

Medicinal

The Cannabaceae family is known for its medicinal applications:

• Cannabis (Cannabis sativa): The cannabinoids in cannabis, such as THC and CBD, are used to treat a variety of medical conditions, including chronic pain, anxiety, chemotherapy-induced nausea, and more. CBD in particular is used in therapeutic products to reduce inflammation and has antipsychotic properties.
• Psychoactive and Therapeutic Effects: Cannabis sativa is used for its psychoactive effects in recreational settings, but also for its therapeutic benefits, especially in the treatment of pain, muscle spasticity, and neurological disorders.

Cosmetics

Hemp oil and other derivatives from Cannabis sativa are used in cosmetics for their nourishing and moisturizing properties:

• Moisturizing: Hemp oil is used in creams, lotions, and soaps for its hydrating and soothing properties, helping to keep the skin soft and healthy.
• Antioxidant: Hemp extracts, particularly CBD, are used in skincare products for their antioxidant and anti-inflammatory properties, helping to protect the skin from environmental damage.

Food

Hemp seeds are used as a food source due to their high nutritional value:

• Hemp Seeds (Cannabis sativa): Hemp seeds are rich in proteins, fiber, and essential fatty acids. They are consumed raw, toasted, or used to make hemp milk, butter, and oil.
• Hemp-Based Foods: Hemp oil and hemp flour are used in a variety of food products, including snacks, protein bars, and baked goods.

Environmental

Plants in the Cannabaceae family contribute to the environment:

• Hemp Fiber: Hemp fiber is used to produce eco-friendly and biodegradable materials, reducing the environmental impact compared to synthetic materials.
• Soil and Biodiversity: Hemp plants are useful in improving soil health and can be used in crop rotation systems to enhance soil quality.

Environmental and Safety Considerations

While plants in the Cannabaceae family offer many benefits, there are some considerations:

• Toxicity: Cannabis sativa is generally safe when used appropriately, but the use of THC in large amounts can lead to unwanted psychoactive effects, such as altered perception and coordination.
• Sustainability: Hemp cultivation should be managed sustainably to avoid excessive resource use and to ensure that agricultural practices do not harm the environment.

INCI Functions

• Antioxidant: Protects the skin from oxidative damage.
• Anti-inflammatory: Reduces inflammation and soothes irritated skin.
• Moisturizing: Helps hydrate and retain moisture in the skin.
• Nourishing: Provides essential nutrients to the skin and hair.

Conclusion

The Cannabaceae family is an important group of plants that provide valuable resources, including seeds rich in essential oils, high-quality fiber, and medicinal compounds. Cannabis sativa (hemp) is the most well-known species, used extensively for its nutritional, medicinal, and industrial applications. With its therapeutic properties and nutritional value, hemp continues to be an important natural resource.
