Question explored with the scientific record
what is the most effective telemase enzyme and in which herb is it founf?
The short version: the evidence you retrieved does not answer your question. It contains no study that compares different telomerase enzymes for effectiveness, and no herb is identified as a source of any such enzyme.
You asked about the most effective "telemase enzyme" and which herb it is found in. I think you meant telomerase, the enzyme that lengthens telomeres. The retrieved studies are about synthetic telomerase inhibitors [1], the structure of human telomerase RNA [8], and the role of telomerase in cancer and aging [3, 4, 7]. None of them test or compare different versions of the enzyme itself for effectiveness. One study shows that diosgenin from fenugreek extract can reduce hTERT gene expression in lung cancer cells [10], but that is an inhibitor, not a more effective form of the enzyme. Another study screened essential oils and found that basil and rosemary oils protected telomere length without upregulating telomerase [18], which is the opposite of what you are asking about.
The idea that different telomerase enzymes exist in herbs with varying effectiveness is not supported by the evidence here. The retrieved studies focus on human telomerase, its regulation, and synthetic or natural compounds that inhibit it. No herb is identified as a source of a telomerase enzyme, and no comparison of enzyme effectiveness across any source is reported.
My call: the evidence does not support the existence of a "most effective telemase enzyme" found in an herb. Confidence: high, because the retrieved studies are on a different topic entirely.

Synthesis, biological evaluation, 3D-QSAR studies of novel aryl-2H-pyrazole derivatives as telomerase inhibitors
A series of aryl-2H-pyrazole derivatives bearing 1,3-benzodioxole or related moieties inhibit telomerase; among them, 16A is the most potent telomerase inhibitor (IC50 = 0.9 μM) and shows antiproliferative activity against B16-F10 (IC50 = 5.34 μM) and SGC-7901 (IC50 = 18.07 μM);…

G-Quadruplex Structures in the Human Genome as Novel Therapeutic Targets
G-quadruplex stabilizers inhibit telomerase, down-regulate oncogene promoters, and can trigger DDR or senescence, with TERRA as a natural telomerase inhibitor; collectively, G4 ligands offer multi-target anticancer potential with resistance considerations.

Telomere position effect: regulation of gene expression with progressive telomere shortening over long distances
Telomere length regulates gene expression at long distances via TPE-OLD through telomere-length–dependent chromatin looping, with long telomeres forming loops that bring subtelomeric genes near telomeres and shortening disrupting these loops, altering expression; telomerase reac…

Levels of telomerase catalytic subunit mRNA as a predictor of potential malignancy.
hTERT mRNA levels significantly correlate with telomerase activity in HCC tumor tissues (r=0.751) and are significantly higher in tumors than non-cancerous liver, suggesting hTERT mRNA could replace telomerase activity for HCC genetic screening.
