BloomWellOn a label, senna appears as Cassia angustifolia, Cassia acutifolia, senna leaf, Alexandrian or Tinnevelly senna, or as its actives, sennosides. Look for those words.
Senna is one plant that wears several names on an ingredient panel, so two boxes can list the same herb and look unrelated to a shopper reading fast.
The LiverTox monograph from the National Institute of Diabetes and Digestive and Kidney Diseases names the commonly used species as Cassia acutifolia, called Alexandrian senna, and Cassia angustifolia, called Indian or Tinnevelly senna. Same shrub, different printing.
So the words to hold in your head are not one word but a small set. Cassia acutifolia. Cassia angustifolia. Alexandrian senna. Tinnevelly senna. Senna leaf. Sennosides. Any one of them on a panel points back to the same shrub described in that NIDDK monograph.
None of this is hidden in fine print by accident, and none of it requires a botany degree to catch. It requires knowing that the plant answers to more than one name, and that the front of a box rarely uses the one you would recognize.
Two reasons, and neither is a trick. Botanists reclassified the genus, so older Cassia names and newer Senna names both circulate on packaging printed in different years. A box from one supplier and a box from another can be describing identical material.
Suppliers also list the plant part rather than the plant itself: senna leaf, senna pod, senna fruit. That reads like a milder ingredient to most shoppers. It is not a different herb and it is not a weaker one. Leaf and pod both carry the actives.
All of it traces back to the same shrub described in that NIDDK monograph. The naming is history and supply-chain habit stacked on top of each other, printed onto a panel that has no room to explain itself.
“The word senna may never appear. Cassia angustifolia, senna leaf, and sennosides are the same plant wearing three different coats on the same panel.”
Sennosides are not a separate herb, and this is the name that fools the most people. LiverTox describes them as anthraquinone derivatives and their glucosides, referred to as senna glycosides or sennosides. When a panel prints sennosides in milligrams, it is telling you the laxative dose.
They are not absorbed the way most ingredients are. Colonic bacteria hydrolyze them, releasing rhein and rhein-anthrone, which act on the colon. That is the whole reason the dose is stated in milligrams and paired with a duration limit rather than a serving suggestion.
LiverTox states the typical dose as 15 to 30 mg of sennosides twice a day, for short term use only. A number in that range on a supplement facts panel is not decoration. It is the same figure a pharmacist would read off a laxative box.
"The active components in senna extracts are anthraquinone derivatives and their glucosides, referred to as senna glycosides or sennosides. The typical dose is 15 to 30 mg of sennosides twice a day, for short term use only."
Mostly in the detox and slimming tea aisle, which is exactly where a shopper is least expecting a stimulant laxative.
A 2026 mini-review in Frontiers in Nutrition reported a content analysis of 12 diet teas sold across three Asian grocery stores in Connecticut, finding that 91.7 percent contained senna leaf, a laxative, while the packaging emphasized slimming imagery and natural claims that may obscure health risks.
That is one sample of stores, not a national count, and it is worth holding it as what it is. Still, it says something plain about the shelf. The front of those boxes was selling a slimming idea while the ingredient panel carried a laxative herb.
Which is why the panel matters more than the front. The imagery is written to be believed. The ingredient list is written to be accurate.
Thirty seconds is enough, standing in the aisle with the box in your hand. One, scan the ingredient list for cassia, senna, or sennoside in any spelling. Two, check the supplement facts panel for a milligram figure next to sennosides.
Three, read the directions for a duration limit. LiverTox states short term use only for senna, and a product carrying it generally states its own window in the directions. Four, look for the word laxative or overnight relief, which signals the stimulant category rather than a daily drink.
Four passes, in that order, and the box has told you what it is. No pass requires you to know botany, only to know the six or seven words this article has already handed you.
This is the comparison most shoppers are actually making, once the names stop being a fog. A stimulant laxative herb carries a dose figure in milligrams and a short-use warning, because that is what the category requires of it.
A gentle daily blend reads differently on the panel. It leads with carminative and adaptogenic herbs instead, and there is no laxative milligram figure to find. That difference is visible in the ingredient list before you ever read a marketing line.
All Day Slimming Tea is one option in that second group, and the maker publishes its own full ingredient explanation. BloomWell did not create it and makes no health claims about it. Read its panel with the same four passes you would use on any other box.

The dose and the window are on the label for a reason, and they are not a shopper's call to make alone. LiverTox frames senna as short term use only, and a duration limit printed in the directions is the manufacturer saying the same thing in its own words.
If you are taking a stimulant laxative past the duration its own directions state, that is a conversation for your doctor rather than a judgment call at the kitchen counter. The same goes for persistent constipation, cramping, or bowel changes.
BloomWell is an editorial brand and this is not medical advice. What this page can do is tell you which words on a panel are worth bringing to that appointment, and what the label already says about how long a product was meant to be used.
You do not need a botany degree to shop well. You need three words in your pocket, cassia, senna leaf, and sennosides, and the habit of turning the box over before it goes in the cart.
Those three words unlock the rest. Cassia pulls up Cassia angustifolia and Cassia acutifolia, Indian and Alexandrian senna. Senna leaf pulls up pod and fruit. Sennosides pulls up the milligram figure and the short-use window that comes with it.
That small act of reading is the whole difference between choosing a product and being chosen by its front panel. Read the maker's full ingredient list and judge it yourself.
Senna's actives are anthraquinone derivatives called senna glycosides, or sennosides, at a typical dose of 15 to 30 mg twice a day, for short term use only. [1]
Indian or Tinnevelly senna. Same plant, older botanical name on the panel.
The plant part, not a milder herb. Leaf and pod both carry the actives.
The active glycosides. A milligram figure here is the laxative dose.

| Senna leafSenna alexandrina | Plant part of senna | Stimulant | Short term |
| Sennosides | The active glycosides | Dose in mg | Short term |
Yes. LiverTox lists Cassia angustifolia as Indian or Tinnevelly senna, and Cassia acutifolia as Alexandrian senna. Both are senna. The label may print either name, or the newer Senna genus spelling.
Generally yes. LiverTox describes senna as a laxative and stimulant used for centuries, and notes it appears in herbal teas used for purging. Check the directions for a duration limit.
A Frontiers in Nutrition mini-review cites an analysis of 12 diet teas in Connecticut where 91.7 percent contained senna leaf. That is one sample of stores, not a national figure.
That is a question for your own doctor, not for a label. Products carrying a stimulant laxative herb state their own duration limits in the directions, and BloomWell does not give medical advice.
The maker sells single tins and multi-month bundles, and lists both on its own page.
