Background: Osteoarthritis (OA) ranks fifth among all forms of disability affecting 10% of the world population. Current treatments available are associated with multiple side effects and do not slow down the progression of the disease. Moreover, no such effective treatment is available to date in various systems of medicine to treat osteoarthritis. Curcumin and Arnica have shown evident clinical advances in the treatment of osteoarthritis. Objective: The aim of the present study was to design, optimize and characterize novel herbal transdermal patches of curcumin and Arnica montana using factorial design. Methods: A multiple factorial design was employed to investigate the effect of hydroxypropyl methyl cellulose, ethyl cellulose and jojoba oil on elongation and drug release. Transdermal patches were evaluated by FTIR, DSC, FESEM, ex vivo drug permeation, anti osteoarthritic activity and analgesic activity. Results: Independent variables exhibited a significant effect on the physicochemical properties of the prepared formulations. The higher values of drug release and elongation were observed with the higher concentration of hydroxypropyl methylcellulose and jojoba oil. Anti osteoarthritic activity was assessed by complete Freund's adjuvant arthritis model; using rats and analgesic activity by Eddy's hot plate method, using mice. Combination patch exhibited good anti osteoarthritic and analgesic activity as compare to individual drug patches. Conclusion: The design results revealed that the combination patch exhibited good physicochemical, anti osteoarthritic and analgesic activity for the treatment of osteoarthritis in animals. More plants and their combinations should be explored to get reliable, safe and effective formulations that can compete with synthetic drugs.

Jojoba is a widely used medicinal plant that is cultivated worldwide. Its seeds and oil have a long history of use in folklore to treat various ailments, such as skin and scalp disorders, superficial wounds, sore throat, obesity, and cancer; for improvement of liver functions, enhancement of immunity, and promotion of hair growth. Extensive studies on Jojoba oil showed a wide range of pharmacological applications, including antioxidant, anti-acne and antipsoriasis, anti-inflammatory, antifungal, antipyretic, analgesic, antimicrobial, and anti-hyperglycemia activities. In addition, Jojoba oil is widely used in the pharmaceutical industry, especially in cosmetics for topical, transdermal, and parenteral preparations. Jojoba oil also holds value in the industry as an anti-rodent, insecticides, lubricant, surfactant, and a source for the production of bioenergy. Jojoba oil is considered among the top-ranked oils due to its wax, which constitutes about 98% (mainly wax esters, few free fatty acids, alcohols, and hydrocarbons). In addition, sterols and vitamins with few triglyceride esters, flavonoids, phenolic and cyanogenic compounds are also present. The present review represents an updated literature survey about the chemical composition of jojoba oil, its physical properties, pharmacological activities, pharmaceutical and industrial applications, and toxicity.

Currently, formulations of skin moisturizers are derived from natural compounds. Fixed oils are known to have compounds that potential to be developed as skin moisturizers based on emollient mechanism. Therefore, this study aims to determine the effect of oil type on the physical characteristics of skin moisturizer creams. In this study, a skin moisturizer cream was formulated using three types of fixed oils: VCO (F1), Olive Oil (F2), and Jojoba Oil (F3). All formulas were tested for physical characteristics of pH, cream type, viscosity, spreadability, and homogeneity. The test results show that all formulas appropriate to the skin pH range,  have o/w type creams and homogeneous texture. In the results of the viscosity test, there was a significant difference (p<0.05) with the highest value of viscosity for F2 (16750 ± 250 cP) > F3 (14200 ± 346cP) > F1 (5833 ± 58 cP), while for spreadability test there were also significant differences (p<0.05) with the highest diameter for  F1 (5.8 ± 0.1 cm) = F3 (5.7 ± 0.2 cm) > F2 (4.3 ± 0.2 cm). Based on the results, it can be concluded that the type of oil can affect the physical characteristics of the moisturizer formula. F1 and F3 have better physical characteristics than F2.
