Product Introduction
Rhubarb Extract – Premium Natural Botanical Ingredient from Kingherbs Limited
Rhubarb Extract, made from Rheum palmatum L. root and rhizome, contains carefully measured bioactive anthraquinones such chrysophanol, rhein, and emodin. HPLC-verified total anthraquinone concentration ranges from 1% to 5% in Kingherbs' product, with 4:1 and 10:1 extraction ratios to fulfil varied formulation needs. This concentrated extract overcomes industrial issues such unpredictable active ingredient levels in raw materials, low water solubility in final goods, and the need for clean-label synthetic laxative alternatives, unlike raw pulverised root powder. Our 25 years of botanical extraction experience and full traceability from approved planting bases provide batch-to-batch uniformity in colour (fine orange-yellow powder), solubility, and bioactive concentration.

FAQ
Q: What are the product's major health benefits?

Q: How does the product operate and explain its active ingredients?
A: BENEFITIVE intestinal microorganisms activate laxative anthraquinone chemicals such rhein and emodin. Linleyin, an estrogen-like molecule, may assist menopause and glucose metabolism. Through NF-κB pathway regulation, anti-inflammatory action occurs.
Q: Do side effects or safety issues exist?
A: usage as indicated for short-term usage is safe. Use beyond two weeks is not advised. Increased dosages may induce stomach pain. Kidney or liver stress may result from long-term usage. Leaves contain harmful oxalic acid, thus only the root/rhizome should be utilised. Avoid additional dosages when pregnant or breastfeeding.
Q: How do 4:1 and 10:1 extraction ratios differ?
A: From 10 kilograms of raw root to 1 kg of extract, a 10:1 ratio increases concentration and potency. It's gentler at 4:1. Choose based on formulation goals and dose strength.
