Read Botanicals can affect gut pathogens/parasitic burden, but the antiparasitic claim is compound-specific and not established for the undisclosed Coxktail blend.

Read Phytogenic blends improve nursery-piglet performance and gut morphology in meta-analysis — the best-supported of the three.
2024
Effects of phytogenic additives and antibiotics in unchallenged nursery piglets: a meta-analysisPooled: phytogenic additives improved nursery-piglet performance and gut morphology; combined phytogenic blends gave an 11.1% higher villus-height:crypt-depth ratio than antibiotics, and outperformed isolated single extracts.
Bottom line. Phytogenic blends as a class are supported for nursery-piglet performance and gut morphology by meta-analysis (blends outperform single extracts and rivalled antibiotics on villus:crypt ratio) — this underpins the Phytoboost performance claim.

Discussion — grounded in the evidence
Phytogenic blends as a class are supported for nursery-piglet performance and gut morphology by meta-analysis (blends outperform single extracts and rivalled antibiotics on villus:crypt ratio) — this underpins the Phytoboost performance claim.
As acidifier alternatives/gut-hygiene aids, plant extracts can reduce post-weaning diarrhoea, but effects are variable and product-specific.
The antiparasitic claim (Coxktail) is the least supported — botanical antiparasitic effects are inconsistent and no product-level data were retrievable.
Crucially, the compositions of these blends are undisclosed, so the class evidence cannot be tied to the specific products, and dose cannot be benchmarked.
Moderate strength overall: a real phytogenic evidence base, but product-specific efficacy and composition are not established.
Where studies disagree: Phytogenic effects are strongly compound- and dose-specific; results vary between products and between challenge and unchallenged conditions. The Green Solution products' compositions are undisclosed, so the class evidence cannot be tied to these specific blends.
Gaps: No product-specific (Coxktail/Purifeed/Phytoboost) trials were retrievable. The antiparasitic claim in particular lacks retrievable product-level evidence; botanical antiparasitic effects are inconsistent.
Manufacturer’s stated mechanism (their words): A range of plant-extract (phytogenic) blends: Coxktail aimed at intestinal parasites, Purifeed positioned as a natural alternative to acidifiers for feed/gut hygiene, and Phytoboost for performance and feed intake. Phytogenics act via antimicrobial, anti-inflammatory and antioxidant properties of their botanical constituents and can improve gut morphology and palatability.
