Humans and micro-organisms have co-evolved having a synergetic relationship with their resident microbiome. The mouth features a diverse microbiota that grows on oral surfaces as functionally and structurally organized biofilms. The oral biofilms are accountable for causing a wide range of chronic diseases and owing to the development of antibiotic-resistant bacteria it has really become tough to treat with efficacy. Operative control of oral biofilm and the resulting infectious diseases epitomizes a significant universal challenge. For this kind of therapeutics, natural herbal products are perfect candidates because of their unique properties. The current review presents a novel approach to control and eradicate oral biofilm by the phytochemicals. Research on phytochemicals is zealously focused on health promotion, disease prevention, and also on the development of novel therapeutic interventions.

Aim/Background: Rural and Urban dwellers in Nigeria claim to treat their arthritis with Olax subscorpioidea root extracts. One of the reasons they chose this treatment is that it is effective and cost less than orthodox drugs with their accompanying side effects. Hence the aim of this study is to investigate the anti-arthritis effects of Olax subscorpioidea Afzel ethanol and aqueous root extracts on chicken type II-Complete Freund{\textquoteright}s adjuvant (CFA) induced arthritis rat model. Materials and Method: The anti-arthritic potential of ethanol and aqueous root extracts of Olax subscorpioidea was evaluated using the chicken type II-Complete Freund{\textquoteright}s adjuvant model in 135 female wistar albino rats. The rats were treated with aqueous and ethanol root extracts of Olax subscorpioidea at varying doses and standard indomethacine drug. Results: The ethanol and aqueous root extracts of Olax subscorpioidea showed significant anti-arthritic activity that was statistically similar to that of indomethacine. Our results suggest that the alcoholic extract of Olax subscorpioidea showed significant (P\<0.05) anti-arthritic potential.

Solvent fractions and decoction of Eleusine indica leaves were tested for their ability to inhibit angiotensin-converting enzyme (ACE), an important component of the Renin-Angiotensin- Aldosterone System which is a critical regulator of arterial blood pressure. The ACE inhibitory activity of each fraction was measured by employing a colorimetric assay based on the hydrolysis of histidyl-hippuryl-leucine (HHL) by ACE. Preliminary assay results revealed that the ethyl acetate fraction exhibited the highest antihypertensive activity with a percent inhibition of 51.51\%. This fraction was considered for further isolation using a bioassay-guided fractionation scheme.

Several extracts from Philippine medicinal plants used for asthma and other inflammatory diseases were evaluated for their ability to inhibit the action of 15-lipoxygenase. The inhibitory activity was tested spectrophotometrically using quercetin as positive control. Eleven species belonging to 11 families displayed varying inhibitory activities. Commelina diffusa and Euphorbia hirta showed the highest inhibitory activity at 51.3\% and 48.5\%, respectively. These plants may contain new 15-lipoxygenase inhibitors.
