cold pressed marigold flower extract
Also known as: Calendula officinalis, Tagetes erecta, Marigold flower extract, Pot marigold, African marigold
Overview
Marigold flower extracts are derived from the flowers of *Calendula officinalis* (pot marigold) or *Tagetes erecta* (African marigold). These extracts are known for their rich content of carotenoids, particularly lutein and zeaxanthin, as well as flavonoids and phenolic compounds. Commonly used in skincare and wound healing products, marigold extract is also taken as a dietary supplement for its potential antioxidant and anti-inflammatory benefits. Research on marigold extracts is moderately developed, with promising in vitro and animal studies, but more high-quality human trials are needed to confirm its health effects. Cold-pressed extracts may offer a unique profile, but specific research on this form is limited. The quality of available evidence is variable, highlighting the need for further investigation into its efficacy and safety in human populations.
Benefits
Marigold flower extract exhibits anti-inflammatory and antioxidant activities, primarily demonstrated in in vitro and animal studies. These effects are attributed to the presence of carotenoids, flavonoids, and phenolic compounds. While human evidence is limited, potential benefits include wound healing and skin health improvements. Marigold extracts may be beneficial for individuals seeking natural anti-inflammatory or antioxidant supplements. However, specific effect sizes and the time course of benefits are not well-documented in human studies, underscoring the need for more rigorous clinical trials to validate these potential health benefits.
How it works
Marigold flower extract's mechanism of action involves the modulation of inflammatory pathways and antioxidant defense mechanisms. It interacts with the immune and skin systems, potentially inhibiting nitric oxide production and modulating inducible nitric oxide synthase (iNOS). The extract's active compounds, such as carotenoids and flavonoids, contribute to its antioxidant properties by neutralizing free radicals. However, the absorption and bioavailability of cold-pressed extracts are not well-studied, requiring further research to understand how these extracts are processed and utilized by the body.
Side effects
Marigold flower extract is generally considered safe when used appropriately, but specific data on cold-pressed extracts are limited. Common side effects are not well-documented, but potential adverse reactions include allergic reactions or gastrointestinal upset. Although rare side effects are not reported, caution is advised in individuals with allergies to plants in the Asteraceae family. Drug interactions may occur with blood thinners or diabetes medications due to the extract's anti-inflammatory effects. Contraindications include pregnancy and breastfeeding due to a lack of safety data. It is essential to consult a healthcare provider before use, especially for individuals with pre-existing health conditions or those taking medications.
Dosage
The minimum effective dose for cold-pressed marigold flower extract is not established. Optimal dosage ranges are typically based on concentrations used in in vitro studies, such as 10-50 μL for anti-inflammatory effects. The maximum safe dose is also not established. Timing considerations are not specified, and cold-pressed extracts may have different bioavailability compared to other forms. Absorption factors are not well-studied, and required cofactors are not established. Due to the limited research, it is crucial to follow product-specific recommendations and consult a healthcare provider for personalized guidance.
FAQs
