“…It has been suggested that the number that can be responsible for fatal poisoning by released cyanide varies from 11 to 21 bitter almonds (Zebbiche et al., 2013). Different treatments have been proposed to reduce the cyanide content of bitter almond oil such as baking, microwave, water boiling, sodium bicarbonate solution, and ultrasonic treatment (Dicenta et al., 2002; Liu et al., 2017; Zhang et al., 2019). No cases of poisoning have been reported for sweet almond oil in available clinical data.…”

Almond oil, a rich source of macronutrients and micronutrients, is extracted for food flavorings and the cosmetics industry. In recent years, the need for high‐quality and high‐quantity production of almond oil for human consumption has been increased. The present review examines the chemical composition of almond oil, storage conditions, and clinical evidence supporting the health benefits of almond oil. From the reviewed studies, it appears that almond oil contains a significant proportion of poly and monounsaturated fatty acids, with oleic acid as the main compound, and an important amount of tocopherol and phytosterol content. Some variations in almond oil composition can be found depending on the kernel's origin and the extraction system used. Some new technologies such as ultrasonic‐assisted extraction, supercritical fluid extraction, subcritical fluid extraction, and salt‐assisted aqueous extraction have emerged as the most promising extraction techniques that allow eco‐friendly and effective recovery of almond oil. This safe oil was reported by several clinical studies to have potential roles in cardiovascular risk management, glucose homeostasis, oxidative stress reduction, neuroprotection, and many dermatologic and cosmetic applications. However, the anticarcinogenic and fertility benefits of almond oil have yet to be experimentally verified.

A study is conducted to explore the under‐utilized resources of Swida wilsoniana seed oil (SWSO). Physicochemical properties of four cultivars of SWSO and their fatty acid composition, phytochemicals, oxidation stabilities, and antioxidant capacities are evaluated. The results indicate that SWSO is abundant in unsaturated fatty acids (76.02–82.43%) and contained a high phytochemical content. Gamma‐tocotrienol (206.03 ± 0.21–215.84 ± 0.17 mg kg−1), β‐amyrin (107.12 ± 0.27–192.30 ± 1.17 mg kg−1), and betulin (32.82 ± 0.59–88.20 ± 0.37 mg kg−1) are major components of SWSO compared to familiar oils. The induction period (5.08–5.80 h) is negatively correlated with unsaturated fatty acid content (r = −0.948**, P < 0.01), particularly linoleic acid (r = −0.938**, P < 0.01). A high antioxidant capacity is observed in SWSO which is primarily attributed to tocopherol/tocotrienol content (0.832*–0.963**). SWSO can be regarded as a new resource and a high‐quality ingredient for dietary foods and other applications. Practical applications: The favorable physicochemical characteristics and functional properties of SWSO indicate that it may be used as a novel and daily edible oil through moderate refining. It also exhibits promise to protect the artery and liver as a special oil for use as shortening and frying because of its ideal FAC and antioxidant capacity. In addition, SWSO may be suitable for the cosmetics industry. Furthermore, more varieties should be obtained to verify and refine the correlations between chemical composition and antioxidant properties. In addition, the specific phenolics in SWSO should be identified to better characterize the relationship between polyphenol content and antioxidant capacity.

“…Thus, the composition of EOs represents the final image including the respective biosynthetic fingerprint but also the modified substances due to preceding processing. Furthermore, in some cases, individual compounds are intentionally removed because of their toxicity, such as hydrogen cyanide from bitter almond oil or methyl eugenol from rose oil ( Rusanov et al, 2012 ; Zhang et al, 2019 ). One important modified oil, e.g ., by increasing the cineole content, while reducing the acid content, is eucalyptus oil ( European Medicines Agency, 2014 ).…”

Essential Oils as Multicomponent Mixtures and Their Potential for Human Health and Well-Being

Essential oils (EOs) and their individual volatile organic constituents have been an inherent part of our civilization for thousands of years. They are widely used as fragrances in perfumes and cosmetics and contribute to a healthy diet, but also act as active ingredients of pharmaceutical products. Their antibacterial, antiviral, and anti-inflammatory properties have qualified EOs early on for both, the causal and symptomatic therapy of a number of diseases, but also for prevention. Obtained from natural, mostly plant materials, EOs constitute a typical example of a multicomponent mixture (more than one constituent substances, MOCS) with up to several hundreds of individual compounds, which in a sophisticated composition make up the property of a particular complete EO. The integrative use of EOs as MOCS will play a major role in human and veterinary medicine now and in the future and is already widely used in some cases, e.g., in aromatherapy for the treatment of psychosomatic complaints, for inhalation in the treatment of respiratory diseases, or topically administered to manage adverse skin diseases. The diversity of molecules with different functionalities exhibits a broad range of multiple physical and chemical properties, which are the base of their multi-target activity as opposed to single isolated compounds. Whether and how such a broad-spectrum effect is reflected in natural mixtures and which kind of pharmacological potential they provide will be considered in the context of ONE Health in more detail in this review.
