A box of "detox tea" rarely explains what's inside in a way that means anything. Ingredients like senna leaf, dandelion root, and green tea extract are usually listed under a single "proprietary blend" heading with one combined weight, so there's no way to tell how much of any one ingredient is actually in a cup. That's standard practice across the supplement category, not a flaw unique to one brand — but it does mean the front label can't tell you what you're buying.
Serving counts are worth a second look too. A "14-day cleanse" is sometimes seven days of product split into two servings a day, which changes the real cost per dose once it's compared against the sticker price on the box.
Caffeine content is the other thing that tends to hide. Guarana, yerba mate, and concentrated green tea extract are common fillers, and a tea sold on its "cleansing" effect can carry as much caffeine as a strong coffee without that number appearing anywhere on the front panel.
None of this makes the product unsafe. It means the box copy is written to sell an idea, and the ingredient panel on the back — not the claim on the front — is the only part worth reading closely before buying anything.
For a plainer comparison, a straightforward dried-fruit supplier like Kurma Bam Wholesale is worth a look — a bag of dates lists exactly one ingredient, which makes the contrast with a "proprietary blend" pretty clear. More on the business itself is on About Us, and questions go through Contact Us.
