We herein report for the first time the synthesis and analgesic properties of silver nanoparticles (Ag-NPs) using buchu plant extract. The as-synthesised Ag-NPs at different temperatures were characterised by UV-Vis spectroscopy, Fourier transform infra-red spectroscopy (FTIR) and transmission transform microscopy (TEM) to confirm the formation of silver nanoparticles. Phytochemical screening of the ethanolic extract revealed the presence of glycosides, proteins, tannins, alkaloids, flavonoids and saponins...

A 52-year-old male presented with signs of acute hepatitis and liver failure. Laboratory investigations for common etiologies were unrevealing, but history suggested liver injury secondary to ingestion of a traditional South African herbal tea made with rooibos and buchu. Livery biopsy confirmed a toxin-mediated liver injury. The patient recovered liver function after stopping the herbal tea. Although hepatotoxicity associated with rooibos and buchu has rarely been reported, anecdotal correspondence with South African physicians confirmed suspected cases...

BACKGROUND: The use of complementary/alternative medicine has garnered rising interest in recent years. Natural products including herbs, vitamins, and minerals are the most popularly consumed. The Internet is a ubiquitous source of information/market for these supplements. AIM: To systematically evaluate the dietary and herbal supplement recommended for patients with CKD and ESRD on the Internet, and try to distinguish between the claim of the manufacturer and proven scientific data...

BACKGROUND/OBJECTIVES: Korean ordinary diets are referred to be good for human health in worldwide. However it is uncertain whether they provide microminerals enough for growth and health of teenagers. A main purpose of this study was to identify micromineral contents in school meals. MATERIALS/METHODS: The fifty cuisines were collected from elementary schools and middle schools in Gyeongnam area. The contents of Fe, Zn, Cu and Mn among microminerals were analyzed by using ICP-OES method...

A characteristic feature of cancer cells is the activation of de novo fatty acid synthesis. Acetyl‑CoA carboxylase (ACC) is a key enzyme in fatty acid synthesis, accelerating the reaction that carboxylates cytosolic acetyl‑CoA to form malonyl‑CoA. ACC is highly expressed in several types of human cancer and is important in breast and prostate cancer cell growth. The aim of the present study was to investigate the effects of 5‑tetradecyloxy‑2‑furoic acid (TOFA), an allosteric inhibitor of ACC, on the proliferation and cell cycle progression of the ovarian cancer cell lines COC1 and COC1/DDP...

A 2-year-old girl presented with intermittent dysuria. Following triage in paediatric A+E, the nursing staff became concerned with the large sample of colourless urine she produced, which tested positive for leucocytes. She was described as a 'big drinker' to the SHO, raising concerns about diabetes insipidus. On detailed questioning it emerged that she had recently drunk a herbal tea preparation (buchu, couchgrass, marshmallow and plantain) to help 'flush out' her urinary system. She was advised to stop the tea...

Bare metal and drug-eluting coronary stents suffer an inherent lack of vascular cell and blood compatibility resulting in adverse patient responses. We have developed a plasma-activated coating (PAC) for metallic coronary stents that is durable, withstands crimping and expansion, has low thrombogenicity and can covalently bind proteins, linker-free. This has been shown to enhance endothelial cell interactions in vitro and has the potential to promote biointegration of stents. Using the rabbit denuded iliac artery model, we show for the first time that PAC is a feasible coating for coronary stents in vivo...

The aim of this study was to investigate the role of metformin in the regulation of development and metastasis of ovarian carcinoma cell lines in vitro and ovarian cancer in a nude mouse model in vivo. The effects of metformin on the ability of two high-metastatic potential human ovarian cancer cell lines (SKOV3 and HO8910-PM) to adhere, invade and migrate in vitro were observed by means of a cell adhesion test, cell invasion test and cell migration test. The size and number of the inoculated and metastatic tumours in vivo in a nude mouse were determined following intraperitoneal injection of metformin...

Dihydroartiminisin (DHA), the active component of a Chinese herb (Artemisia annua), has been utilised as an anti-malarial drug since ancient China. DHA has also been shown to inhibit proliferation of cancer in vitro. However, the capacity of DHA to inhibit the development of ovarian cancer is still unclear. The adhesion, invasion, and migration of human ovarian cancer cell line (HO8910PM) was determined following DHA treatment in vitro, using Matrigel coated plate, transwell membrane chamber, and wound healing models, respectively...

South Africa has offered the world two indigenous aromatic plants from which commercially important natural products have been developed: Pelargonium graveolens (and its hybrids) the source of geranium oil and Agathosma betulina, from which 'Buchu' oil is produced. Despite the historical use of 'Buchu' and the commercial interest developed around this coveted indigenous resource the (limited) research has not been coherently assembled. This overview aims to unite aspects on the botany, traditional and modern day uses, chemistry and pharmacological data on 'Buchu' which is undeniably one of South Africa's most renowned botanical assets...

The toxicities of 44 plant essential oils against larvae of Cadra cautella (Walker) were examined using direct contact and vapor phase toxicity bioassays and compared with the lethal activity of chlorpyrifos-methyl, diazinon, dichlorvos, and fenthion, four widely used organophosphorus insecticides. Responses varied according to plant material used and exposure dose and time. In a filter paper contact toxicity bioassay, potent toxicity was produced from buchu leaf, niaouli, and rosemary oils at 2.4 mg/cm2 and armoise, cypress, galbanum, and mace oils at 4...

Two improved, simple, selective and sensitive reversed-phase HPLC methods were developed for the determination of diosmin and hesperidin simultaneously or separately, using external or internal standard techniques, respectively. The methods were applied for determination of the diosmin and/or hesperidin in Buchu leaves and pharmaceutical dosage forms (three tablets). The methods involved very simple efficient extraction procedures, the use of a LiChrosorb RP-18 column, a mixture of methanol-water (60:40, v/v) as a mobile phase in an isocratic mode at a flow rate of 1...

The mode of action of essential oils from two buchu species (Agathosma betulina and A. crenulata, Rutaceae) from the Cape region of South Africa has been studied on smooth muscle in-vitro using guinea-pig ileum. At high concentration, the oils had an initial spasmogenic activity followed by spasmolysis. The spasmolytic action was post-synaptic, not atropine-like and did not involve adrenoceptor or guanylyl cyclase activation. In the presence of the phosphodiesterase inhibitor rolipram, the spasmolytic action of A...

Buchu leaves and oil of buchu were used by the indigenous people of South Africa for hundreds of years. The medicinal use of buchu was taken up by the early Dutch settlers and later introduced into the pharmaceutical industry in the UK. Buchu preparations are now used as a diuretic and for a wide range of conditions including stomach aches, rheumatism, bladder and kidney infections and coughs and colds.
