Side Effects of Rhubarb
While rhubarb is packed with benefits, consuming too much can have some downsides:
1. Risk of Kidney Stones & Kidney Damage
- Rhubarb contains oxalates, which can bind with calcium in the body and form kidney stones.

- Rhubarb’s natural laxative effect can cause diarrhea, cramping, and dehydration if eaten in excess.
- Long-term use as a laxative may lead to dependence and weaken natural bowel function.
3. Interference with Calcium Absorption
- The oxalates in rhubarb bind with calcium, making it harder for the body to absorb this essential mineral.
- Over time, this could lead to calcium deficiency, affecting bone health.
- To reduce the risk, pair rhubarb with calcium-rich foods like dairy or almonds.
4. Toxicity from Rhubarb Leaves (DO NOT EAT)

6. Not Safe During Pregnancy & Breastfeeding (In Large Amounts)
