Centella asiatica, locally well known in Malaysia as pegaga, is a traditional herb that has been used widely in Ayurvedic medicine, traditional Chinese medicine, and in the traditional medicine of other Southeast Asian countries including Malaysia. Although consumption of the plant is indicated for various illnesses, its potential neuroprotective properties have been well studied and documented. In addition to past studies, recent studies also discovered and/or reconfirmed that C. asiatica acts as an antioxidant, reducing the effect of oxidative stress in vitro and in vivo. At the in vitro level, C. asiatica promotes dendrite arborisation and elongation, and also protects the neurons from apoptosis. In vivo studies have shown that the whole extract and also individual compounds of C. asiatica have a protective effect against various neurological diseases. Most of the in vivo studies on neuroprotective effects have focused on Alzheimer’s disease, Parkinson’s disease, learning and memory enhancement, neurotoxicity and other mental illnesses such as depression and anxiety, and epilepsy. Recent studies have embarked on finding the molecular mechanism of neuroprotection by C. asiatica extract. However, the capability of C. asiatica in enhancing neuroregeneration has not been studied much and is limited to the regeneration of crushed sciatic nerves and protection from neuronal injury in hypoxia conditions. More studies are still needed to identify the compounds and the mechanism of action of C. asiatica that are particularly involved in neuroprotection and neuroregeneration. Furthermore, the extraction method, biochemical profile and dosage information of the C. asiatica extract need to be standardised to enhance the economic value of this traditional herb and to accelerate the entry of C. asiatica extracts into modern medicine.

Sample of tapeworm was isolated from 1 patient in Ha Tay province. It was amplified by polymerase chain reaction (PCR), purified, cloned and sequenced. The nucleotide sequence was comparatively aligned with the known corresponding sequences of Taenia asiatica (Taiwanese); T. saginata (Chinese) and T. solium (Chinese and Vietnamese) and used for establishing a phylogenetic relationship for analysis of identification, using special programs. Molecular-based analysis revealed that the Taenia sp from this patient is identified as Taenia asiatica. Absolute nucleotide similarity (100%) between Taenia asiatica in Ha Tay, Vietnam and Taenia asiatica in Taiwan; the grouping together with T. asiatica (Taiwan) confirmed the sample obtained from Ha Tay is closely related to the Taiwanese T. asiatica

Pentacyclic triterpenes, mainly, asiatic acid, madecassic acid, asiaticoside, and madecassoside are the active constituents of Centella asiatica. A pentacyclic triterpene enriched C. asiatica extract (PRE) was prepared and standardized to contain a total pentacyclic triterpenes not less than 65% w/w. This work was focused on determination of antiinflammatory, antioxidant, and tyrosinase inhibitory activities of PRE and its stability. The PRE exhibited a satisfactory nitric oxide inhibitory effect, with an IC50 value of 64.6 µg/mL. In addition, the PRE inhibited tyrosinase enzyme activity with an IC50 value of 104.8 µg/mL. In contrast, the PRE possessed only weak antioxidant activity. The PRE was stable over a period of four months when stored as a dried powder but only in a well-closed container protected from light at 4 °C. An aqueous alcoholic solution of the PRE was stable at pH values of 5.8 and 7.0, but was not stable at a pH of 8.2. Preparations of the PRE in an aqueous solution should be performed in acidic or neutral conditions.

OBJECTIVES: The aim of this study was to assess the antiplaque and antigingivitis effectiveness of aqueous single-phase and oil-water two-phase mouthrinses, containing bamboo salt, magnolia bark, and Centella asiatica extracts, in Korean adults. METHODS: In this double-blinded clinical trial, a total of thirty-four participants aged over 19 years were randomly allocated to three experimental groups: 1) control group; 2) aqueous single-phase mouthrinse (ASM) group, and; 3) oil-water two-phase mouthrinse (OTM) group. The experimental mouthrinses all contained sodium fluoride, and the ASM and OTM contained additional ingredients of bamboo salt, magnolia bark, and Centella asiatica extracts. For the OTM, 50% essential oil was added to create an oil-water two-phase mouthrinse. A two-week randomized crossover design with a two-week washout period was applied. Following a complete dental prophylaxis, participants were instructed to use the prescribed mouthrinse twice daily for two weeks as an adjunct to their usual mechanical oral hygiene procedures. Pre- and post-experiment clinical examinations were performed to measure the plaque index (PI) and bleeding on probing (BOP) for the full mouth. Paired t-test was applied to compare the intergroup differences for all clinical variables. RESULTS: Compared to the control group, ASM showed a significantly reduced BOP (P<0.05). However, there was no statistically significant difference in the effects of the three mouthrinses on reducing the PI. CONCLUSIONS: The results of this study indicate that the use of an aqueous, single-phase mouthrinse containing bamboo salt, magnolia bark and Centella asiatica extracts could help alleviate gingivitis.

The objective of the present study was to examine the effects of beta-glucan originating from Aureobasidium on full-thickness skin wound healing in diabetic C57BL/KsJ-db/ db mouse models. In the diabetic C57BL/KsJ-db/db model, test articles were topically applied twice a day for 20 days starting from 1 day after wounding. The results were compared to that of MadecassolTM ointment (madecassol; 1% Centella asiatica extracts) topically applied at a concentration of 100 mg/kg. Treatment with beta-glucan resulted in significant (p<0.01 or p<0.05) and dose-dependent decreases in wound size compared with that of vehicle control showing increased wound size (WS, %). In addition, 50% contraction time (CT50) was dramatically and dose-dependently reduced, and inflammatory cells in granulation tissues of the wound area were significantly (p<0.01 or p<0.05) and dosedependently reduced compared with that of vehicle control showing increased numbers of micro-vessels and fibroblasts as well as re-epithelialization. In the madecassol group, similar changes in inflammatory cells and fibroblasts with re-epithelialization were also observed, but madecassol did not influence angiogenesis. No meaningful changes in body weight were detected in all tested groups compared with the vehicle control. Therefore, these data suggest that beta-glucan has a beneficial effect on diabetic delayed skin wound healing and may be useful to manage incurable skin wounds in diabetic animals.

This study was designed to assess the effects of compound madecassol(madecassic acid with neomycin sulfate and hydrocortisone acetate) on the wound healing. Madecassol is a titrated extract of centella asiatica and the clinical effects of madecassol are stated to the enhancement of wound healing and the prevention and relief of excessive scar formation. Compound madecassol is composed of madecassol and neomycin sulfate and hydrocortisone acetate. Neomycin sulfate has antibiotic effect and hydrocortisone acetate has antiinflammatory and antiallergic effects. So, compound madecassol has a synergistic effect of madecassol as well as neomycin sulfate and hydrocortisone acetate. Using 54 rats, we compared the effect of compound madecassol on wound healing at 3rd, 7th, 14th, and 21th postoperative days. This study examined the histologic findings and the gross findings which were wound size, epithelization and quality of granulation tissue. In this study, compound madecassol showed lower degree of inflammatory infiltration, shorter inflammatory phases and less wound contraction. The number of the myofibroblast in the group of compound madecassol were fewer than other groups. Granulation tissue of the compound madecassol was relatively healthier than others. There were no significant difference of re-epithelization between compound madecassol and other groups. In conclusion, compound madecassol can reduce excessive wound contraction and promotes wound healing process.
