The efficacy of extracts from two Piperaceae species, Piper nigrum L. and P. tuberculatum Jacq. were evaluated using larvae and adults of the Colorado Potato Beetle Leptinotarsa decemlineata (Say). Young larvae and neonates were the most susceptible; a 24-h LD(50) of 0.064% extract of P. tuberculatum was determined for 4-day-old larvae, while 0.05% extract of P. nigrum reduced larval survival u...

BACKGROUND Hyperpigmentation disorders are common among those seeking care from dermatologists and primary care physicians. The cosmeceutical and natural product industries are rapidly growing and many botanical agents are purported to improve hyperpigmentation disorders. OBJECTIVE We sought to review clinical evidence for the use of botanical agents in the treatment of hyperpigmentation. M...

Background & Aim: The plants of the greenhouse have been affected by infestation of the pest Trialeurodes vaporariorum, called greenhouse whitefly, which markedly reduced production. Synthetic insecticides have been widely developed and, their extensive use has brought about disadvantages, like environmental disturbance, pest resistance, lethal effects on non target organisms ...

Despite the increasing sales of black cohosh (the dried rhizome and root of Cimicifuga racemosa L.) in the world herbal market, these products have continuous adulteration issues. The botanical authenticity of the black cohosh products is the first important step for ensuring their quality, safety and efficacy. In this study, we genetically identified the botanical sources of 10 black cohosh pr...

Retinoic acid (RA) has been effective for improving wrinkles. However, it has also been reported that RA induces skin irritation. In this study, we explored new botanical compounds that show RA-like activity, but do not induce inflammation in vitro. Keratinocytes were maintained in a confluent condition and induced differentiation. Under this condition keratinocytes were treated with many botan...

Background Botanical supplements with flavonoids possess the ability to reduce inflammatory markers such as CRP, IL-6, and TNF-a. Also, they could potentially help reduce sugarinduced weight gain and facilitate weight loss. Diafin is a non-stimulant, botanical, weight loss product created from a blend of standardized Free-B-ring flavonoids and flavans from two plant extracts isolated from the S...

Formerly used world-wide as a popular botanical medicine to reduce anxiety, reports of hepatotoxicity linked to consuming kava extracts in the late 1990s have resulted in global restrictions on kava use and have hindered kava-related research. Despite its presence on the United States Food and Drug Administration consumer advisory list for the past decade, export data from kava producing countr...

Fifteen plant species were collected from the Nelspruit Botanical Garden based on a list of plants provided by Phytomedicine Programme at the University of Pretoria and their ethnopharmacological information. Hexane, dichloromethane (DCM), acetone and methanolic extracts were screened for antimycobacterial activity against Mycobacterium smegmatis. The acetone extract of Milletia stulhimannii wa...
