Coleus, particularly the species Coleus forskohlii, is widely recognized for its diverse benefits, ranging from cardiovascular support to its appeal as a vibrant ornamental plant. Its primary bioactive compound, forskolin, underpins many of its health-related applications.
Key Health Benefits of Coleus
The extract from Coleus forskohlii has been traditionally used and scientifically investigated for several physiological effects, mainly due to the presence of forskolin.
1. Cardiovascular Support
One of the most significant benefits of coleus is its potential impact on cardiovascular health. Forskolin, a diterpenoid compound found in coleus, has properties that may help dilate blood vessels, leading to improved blood flow. Additionally, it can enhance the forcefulness with which the heart pumps blood, contributing to overall heart function. This dual action can be beneficial for maintaining healthy circulation.
2. Respiratory Health
Coleus has been explored for its bronchodilatory effects, meaning it may help open up the airways. This action is particularly relevant for supporting respiratory comfort and function, as it can ease breathing.
3. Weight Management Potential
Research suggests that forskolin may play a role in fat metabolism. It is believed to stimulate the breakdown of stored fat (lipolysis) and promote a healthy metabolic rate, making it a subject of interest in weight management and body composition goals.
4. Eye Health
Some studies indicate that coleus extract may contribute to maintaining healthy intraocular pressure. This property makes it a subject of interest in supporting ocular health, particularly concerning conditions related to eye pressure.
5. Skin Health
Coleus, through its active compounds, has been investigated for its potential in modulating cellular processes, which may extend to skin health. It's thought to influence cell proliferation and differentiation, which could be relevant in supporting healthy skin.
How Forskolin Works
Forskolin primarily functions by activating an enzyme called adenylate cyclase. This enzyme is crucial for increasing levels of cyclic adenosine monophosphate (cAMP) inside cells. cAMP is a vital secondary messenger that regulates a wide array of biological processes, including:
- Smooth muscle relaxation: Leading to blood vessel dilation and bronchodilation.
- Lipid metabolism: Stimulating the breakdown of fats.
- Cardiac muscle contractility: Improving the heart's pumping action.
- Cellular signaling: Influencing various cell functions.
Ornamental Value
Beyond its health attributes, many varieties of Coleus scutellarioides (often simply called Coleus) are highly prized as ornamental plants for their stunning and diverse foliage.
- Vibrant Colors: Coleus plants come in an astonishing array of colors, including green, yellow, pink, red, maroon, and purple, often with intricate patterns and variegations.
- Versatile Landscaping: They are popular for adding bursts of color to garden beds, borders, containers, and even as houseplants.
- Easy to Grow: Generally low-maintenance, coleus thrives in partial shade to full sun (depending on the variety) and prefers consistently moist soil.
