Luo han guo — called monk fruit in the West — is a small, round fruit that grows in the misty mountains of Guangxi in southern China. In Traditional Chinese Medicine (TCM), it has been valued for centuries as a cooling, moistening food that supports the lungs and throat.

Brewed into tea, the dried fruit produces a deep amber drink with a rich, raisin-like sweetness — yet it contains no added sugar. For anyone who craves something sweet while trying to cut back on sugar, monk fruit tea is one of the most pleasant bridges between ancient food wisdom and modern wellness.

What Is Luo Han Guo?

Luo han guo (Siraitia grosvenorii) is a perennial vine in the gourd family, related to melons and cucumbers. The fruit has been cultivated for centuries in Guangxi province, particularly around the towns of Yongfu and Lingui, where the cool mountain climate is said to give it its characteristic sweetness.

Locals nicknamed it “the immortal fruit” (神仙果, shén xiān guǒ), partly because the dried fruit keeps for a very long time and partly because of its reputation as a gentle throat and lung soother. It appears in the Qing dynasty supplement to the Compendium of Materia Medica (《本草纲目拾遗》), where it is described as sweet and cooling, useful for coughs and dry throat.

Most of the fruit’s sweetness comes from compounds called mogrosides, which are intensely sweet yet contain negligible calories. In TCM practice, the whole dried fruit — shell, flesh, and seeds together — is brewed, not just an isolated extract.

Luo Han Guo in TCM: Properties and Actions

In the TCM framework, every food carries a thermal nature, a taste, and a set of organ pathways (meridians). Luo han guo is described as:

Because it is cool and sweet, luo han guo is traditionally used to:

In TCM theory, dryness and heat often disturb the Lung, which governs the skin and respiration and is considered especially sensitive to dry environments. A cool, moistening food like monk fruit is believed to help balance that pattern.

Sweet Without Sugar: The Modern Appeal

Monk fruit has found a second life in the modern wellness world as a natural zero-calorie sweetener. Mogrosides are reported to be roughly 150–300 times sweeter than table sugar, and some studies suggest they do not raise blood sugar the way sucrose does.

For everyday tea drinking, this means you can brew a genuinely sweet, satisfying drink without reaching for honey or sugar. People who follow low-sugar diets, parents who want to limit their children’s sugar intake, and anyone who simply prefers natural sweetness all have a reason to keep a few dried fruits in the pantry.

How to Make Luo Han Guo Tea

The classic preparation is almost embarrassingly simple — the fruit does all the sweetening work itself.

Classic Monk Fruit Tea

Ingredients:

Steps:

  1. Rinse the dried fruit under running water. Crack the shell lightly with the back of a spoon — it is brittle and opens easily — so the flesh is exposed.
  2. Drop the pieces into a pot and add the water.
  3. Bring to a boil, then lower the heat and simmer for 15–20 minutes, until the water turns a deep amber-gold and smells richly sweet.
  4. Strain into cups and drink warm. The tea keeps in the fridge for 2–3 days and can be reheated or served cold.

Tip: one dried fruit can be brewed twice. The second brew is lighter but still pleasantly sweet — an economical habit that matches the fruit’s “immortal” reputation.

When to Drink It

Monk fruit tea is a flexible everyday drink, but it shines at specific moments:

Who Should Be Careful

Because luo han guo is cool in nature, TCM tradition advises people with a cold or deficient spleen-stomach pattern — think loose stools, weak appetite, a pale tongue, or constantly cold hands and feet — to drink it less often or to balance it with warming companions such as ginger or red dates.

Finally, monk fruit tea is a food, not a medicine. If a cough, sore throat, or any symptom is severe, persistent, or accompanied by fever, please seek professional medical care.
