Turmeric and Curcumin—Health-Promoting Properties in Humans versus Dogs

Abstract

The growing popularity of the use of nutraceuticals in the prevention and alleviation of symptoms of many diseases in humans and dogs means that they are increasingly the subject of research. A representative of the nutraceutical that deserves special attention is turmeric. Turmeric belongs to the family Zingiberaceae and is grown extensively in Asia. It is a plant used as a spice and food coloring, and it is also used in traditional medicine. The biologically active factors that give turmeric its unusual properties and color are curcuminoids. It is a group of substances that includes curcumin, de-methoxycurcumin, and bis-demethoxycurcumin. Curcumin is used as a yellow-orange food coloring. The most important pro-health effects observed after taking curcuminoids include anti-inflammatory, anticancer, and antioxidant effects. The aim of this study was to characterize turmeric and its main substance, curcumin, in terms of their properties, advantages, and disadvantages, based on literature data.

The Preparation of Curcumin-Loaded Pickering Emulsion Using Gelatin–Chitosan Colloidal Particles as Emulsifier for Possible Application as a Bio-Inspired Cosmetic Formulation

“…Following the optimization of the oil volume fraction and the homogenization speed, it was important to understand whether CMC-GA particles of varying pH levels can yield a stable Pickering emulsion. In order to address this, CMC-GA colloidal particles of varying pH levels (3)(4)(5)(6)(7)(8)(9) were used to emulsify coconut oil in water, using previously optimized conditions (an oil volume fraction of 0.6 and a homogenization speed of 16,000 rpm). The stability of the resulting emulsion was monitored by assessing the phase separation, oil droplet size, and viscosity.…”

“…Furthermore, curcumin also suppresses solar UV ray-induced inflammatory responses by inhibiting the activation of NF-κB and other pro-inflammatory transcription factors [ 2 , 3 ]. Moreover, curcumin is reported for a wide range of medicinal properties, and is also very well tolerated by the human body, even up to 8 g a day, without showing any significant toxicity symptoms [ 4 , 5 , 6 , 7 ]. All these facts have prompted researchers to develop curcumin-based cosmetic formulations, such as sun-screening cream or for general skin care applications [ 8 , 9 ].…”

Male Breast Cancer: Current Scenario and Future Perspectives

“… 57 Turmeric and curcumin, known for their anti-inflammatory and antioxidant properties, may also offer some protective benefits. 58 It is reported that compared to the omega-6 arachidonic acid, marine omega-3 fatty acids such as eicosapentaenoic acid and docosahexaenoic acid have demonstrated a lower associated risk of BC. Regular exercise is also crucial in this context.…”
