Citrus medica, also known as “cedar”, “citron”, “etrog”, “foshou”, and “fingered citron”, belongs to the Rutaceae family and is one of the three basic species of the Citrus genus. It is a short, medium-sized evergreen tree that reaches 4–8 m in height, with leaves up to 20 cm long and flowers growing in groups of three to twelve. The color of the fruit (size 20–30 cm) varies according to the state of maturation from green to yellow.
The species has been valued in traditional medicine for centuries and continues to be widely used in Ayurveda for its potent antioxidant, anti-inflammatory, carminative, antibacterial and antiviral purposes. Modern research has further highlighted its antidiabetic, anticancer, and neuroprotective effects, making Citrus medica a significant natural resource in wellness and therapeutic fields.
The most active and valuable part of the Citrus medica is its peel. In traditional medicine across West Tropical Africa and China, the essential oil derived from this peel is regarded as an antibiotic. It is rich in citroflavonoids and several macronutrients such as sugars, lipids and proteins, although its powerful biological effects are largely attributed to its micronutrient profile. The peel contains more water-soluble vitamins than the pulp, especially vitamins B6, B1, and B2, along with vitamin C and other essential micronutrients like hesperidin (vitamin P) and rutin. Additionally, it is a good source of minerals and non-essential amino acids that nourish and support overall skin health.
When applied in skincare, Citrus Medica Peel Oil delivers potent antioxidant benefits thanks to its high content of ascorbic acid (vitamin C), along with phenolic compounds, flavonoids, carotenoids, and heteropolysaccharides. These components work together to neutralize free radicals that can damage skin cells, helping to prevent visible signs of aging and environmental damage. Its strong anti-inflammatory properties help soothe redness and irritation, making it especially beneficial for sensitive or reactive skin types.
As an antimicrobial, antibacterial and fungitoxic agent, Citrus Medica Peel Oil effectively supports a balanced skin microbiome, reducing breakouts and promoting a clearer, healthier complexion. The oil’s blend of B vitamins, vitamin C, and minerals nourishes the skin deeply, supporting hydration and resilience. Additionally, its natural acids and enzymes provide gentle exfoliation, enhancing skin texture and radiance for a smoother, brighter appearance.
