Allergic contact dermatitis related to para-phenylendiamine (PPD) from temporary black henna tattoos and hair dyes has become an epidemic in recent years. Several cases of adverse skin reactions to PPD have been reported in the literature. Herein, we present a case of angioedema-like allergic contact dermatitis related to hair coloring with henna.

Decorative henna skin painting can provoke severe reactions in the skin. We report 3 cases of unusual and persistent hyperpigmentation following nonpermanent henna tattoo, which alerted us to identify an additional side effect.

Carpal tunnel syndrome (CTS) is the most common diagnosed upper limb compressive neuropathy; though its diagnosis remains controversial. Some patients apply Henna (the extracts of the plant Lawsonia inermis) to their palms to relieve the symptoms. We don’t know how common is this practice and if it does help in clinical diagnosis. The purpose of this study was to examine the diagnostic value of...

Abstract: Decorative henna skin painting can provoke severe reactions in the skin. We report 3 cases of unusual and persistent hyperpigmentation following nonpermanent henna tattoo, which alerted us to identify an additional side effect.

Denture stomatitis is a very common disease affecting the oral mucosa of denture wearers. The aim of this study was to measure the antifungal effect of henna against Candida albicans adhered to acrylic resin as a possible method for prevention of denture stomatitis. One-hundred-eighty acrylic plates were prepared of heat-cured acrylic denture resin. The specimens were divided into six groups of...

Henna (Lawsonia inermis) has been used for centuries as a herbal hair and skin dye, but very little is known about its additives and contaminants that could adversely affect human health. An analytical method was developed to determine organochlorine compounds in henna, as they are still widely used in the areas where henna is grown. Samples were sonicated with n-hexane, extracts cleansed on Fl...

Incidence of cancer is growing swiftly worldwide and sparse supply of anticancer drugs; unaffordable cost and its lethal effect have shown the way to adopt complementary and alternative medicine for the treatment and/or prevention of cancer. The isolation of anti-cancer alkaloids vinblastine, vincristine and podophyllotoxins during 1950s prompts research on anticancer agents from plant origins....

Temporary 'black henna' tattoos, an increasingly popular body decoration in pediatric population, are associated with a growing incidence of adverse events. Black henna does not exist naturally, it is obtained from original henna after the addition of other compounds, among them paraphenilendiamine (PPD), which serves to darken the tattoo and allows greater precision to the design. PPD is known...

In this research, the capabilities of Henna and Henna with chitosan microparticles adsorbents were studied in order to remove the ion Cd (II). Response Surface Method (RSM) and Central Composite Design (CCD) were used to minimize the number of experiments (21 runs) for Henna and (26 runs) for the Henna with chitosan microparticles. The parameters were pH (2-9), initial solution concentratio...

Corrosion behaviour of aluminium alloy inhibited by henna was investigated by using weight loss analysis, Fourier Transform Infrared (FTIR), electrochemical impedance spectroscopy (EIS) and potendiodynamic polarization study. Lawsonia inermis or also known as henna was extracted by using ethyl acetate and methanol. The result from these characterization shows that henna extracted in ethyl aceta...
