In this true experimental study, researchers assessed the antibacterial effect of white jasmine leaf extract against Propionibacterium acnes and found varying inhibition zone diameters, with 500 µg/mL achieving up to 10.95 mm, though less effective than clindamycin, which reached 28.55 mm.

This study found that variations in propylene glycol concentration in wax apple leaf extract hair tonic affected pH, specific gravity, and viscosity, aligning with SNI requirements.

In this study, Platycladus orientalis leaf extract loaded into hyaluronic acid microneedles was found to promote hair follicle growth by enhancing the environment for hair cell proliferation and activating repair pathways, suggesting potential as a treatment for androgenic alopecia.

This study investigated the physical stability of hair tonic formulations made from ethanol extract of cayenne pepper leaves, finding that formulations with specific concentrations of propylene glycol and ethanol had good physical stability.

This study reported that a 4% water fraction of green tea leaf extract showed the most effective hair growth promotion in rabbits.

This study found that aloe vera extract accelerated wound healing in incised rabbit skin.

This study comparatively evaluated different extraction techniques for Schinus terebinthifolius Raddi leaf extracts and found that conventional extraction with ethanol yielded the highest antioxidant activity and beneficial effects on skin cell viability, supporting its potential use in sustainable cosmeceutical formulations targeting skin aging.

This study found that hot water extract of Hydrangea serrata leaf and hydrangenol promoted hair growth by enhancing 5α-reductase inhibitory activity, stimulating dermal papilla cell growth, and exhibiting anti-inflammatory and anti-androgenic effects in cell cultures, mice, and human skin organoid models.

This study explored the effects of hair tonics made from a combination of kelor leaf and fragrant pandan leaf ethanol extracts on rat hair growth, finding that these combinations influenced hair growth when compared to single extract formulations over 28 days.

This study evaluated the anti-alopecia effects of Petroselinum crispum leaf extracts in a rabbit model and through molecular docking analysis, finding that two ethyl acetate fractions promoted hair growth, with effects comparable to minoxidil, suggesting potential for alopecia treatment development.

This study found that Piper nigrum leaf extract showed in vivo anti-androgenic activity and potent 5α-reductase inhibitory effects, with piperine and (−)-cubebin identified as active components.

This study observed that Biota orientalis L. leaf extract may promote hair growth and suppress sebum production in human cells, suggesting potential benefits for hair restoration.

This study found that extracts from Stauntonia hexaphylla leaves and fruits, particularly those with a higher leaf-to-fruit ratio, significantly enhanced osteogenic activity and inhibited osteoclast-related gene expression in vitro, suggesting potential for osteoporosis prevention.

In this study, high-dose oral administration of Ramania leaf ethanol extract in Wistar rats resulted in no significant acute toxicity symptoms, though gastric ulcers and hair loss were observed. The extract is classified as non-toxic under specified guidelines, with an LD50 greater than 5000 mg/kg.

This study found that the ethanol extract of mangkokan leaf (Polyscias scutellarium) demonstrated antibacterial activity against Escherichia coli and Staphylococcus aureus, with higher concentrations showing greater inhibition zones, particularly against Staphylococcus aureus.

This study tested a natural hair dye made from papaya seed extract, celery leaf, and avocado, finding color change in animal hair but also noting tissue changes like hyperkeratosis.

This study found that a cosmetic formula containing 2% Orthosiphon stamineus leaf extract significantly reduced skin oiliness and pore size, showing better results than a formula with 1% zinc gluconate.
