Aromatic broth infused with mountain herbs, served with tender vegetables and protein β deeply nourishing and traditional.
Among Taiwan's sixteen officially recognized indigenous peoples β the Amis, Atayal, Bunun, Paiwan, and others who have inhabited the island's central mountain range and eastern valleys for thousands of years β wild herb soup (sometimes called 'mountain vegetable broth' or, in Amis, 'cafad no riko') occupies a place that goes far beyond ordinary cooking. These communities traditionally harvested mugwort (ai-cao), goji leaf, astragalus root, and other mountain botanicals not simply for flavor but as deliberate medicine: plants chosen for their capacity to strengthen the body against the cold, altitude, and physical demands of highland life. The broth is clear and golden, carrying a pleasantly assertive bitterness that Taiwanese aboriginal cooks consider a sign of quality β 'if it doesn't taste slightly bitter, you haven't cooked it long enough' is a common saying. Pork or chicken is blanched first to remove impurities, then slow-simmered with the herb bundle so that every drop of the broth absorbs the botanicals' essence. The technique is deliberately unhurried. A proper wild herbs soup builds flavor over thirty to forty minutes of gentle simmering at a low rolling boil β around 90β95Β°C β rather than a furious boil that would cloud the broth and destroy delicate aromatic compounds. Root vegetables (carrots, turnip) are added in the final fifteen minutes so they soften without disintegrating, absorbing the herb-infused liquid while contributing their own natural sweetness to balance the bitterness. The finished soup is limpid, fragrant, and layered: first you taste the savory depth of the meat stock, then the vegetal sweetness of the roots, and finally a slow herbal warmth that lingers at the back of the throat. Serving this soup is an act of care in aboriginal Taiwanese households. Elders typically prepare it for family members who are recovering from illness, returning from hard outdoor work, or facing the change of seasons. At communal harvest festivals β particularly the Amis 'Ilisin' β large pots of wild herb broth are cooked communally and ladled out to guests as a gesture of welcome and collective nourishment. Making it at home today, whether you source dried herbs from a Chinese herbal medicine shop or forage seasonal greens from a farmers market, reconnects you with one of East Asia's oldest and most thoughtful cooking traditions.

Place the dried herbs in a bowl with cold water and soak for 5 minutes to remove any dust or grit, then drain. This step also slightly rehydrates the herbs so they release their compounds more evenly during simmering. If using fresh mugwort or goji leaf, simply rinse under cold running water.
Bundle the herbs loosely in a piece of cheesecloth tied with kitchen twine β this makes removal effortless and keeps the broth clean.
Place the sliced pork or chicken in a small saucepan, cover with cold water, and bring to a boil over high heat. Boil for 2 minutes β you will see grey foam rise to the surface. Drain immediately and rinse the meat under cold running water until clean. This blanching step removes blood and impurities and is the reason the finished broth stays clear and light.
Starting with cold water rather than boiling draws out impurities more effectively.
Pour 6 cups of water or light stock into a medium saucepan and bring to a full boil over high heat. Add the herb bundle (or loose herbs) and the blanched protein. Reduce the heat to maintain a gentle rolling simmer β small bubbles breaking steadily at the surface, around 90β95Β°C. Simmer uncovered for 15 minutes, allowing the herbs to perfume the liquid and the meat to cook through.
Resist the urge to rush this at a hard boil; a furious boil clouds the broth and cooks off the delicate aromatic oils in the herbs.
Add the sliced carrots and cubed turnip to the simmering broth. Continue to simmer gently for 12β15 minutes, until the carrots yield easily when pierced with a chopstick but still hold their shape β they should not be mushy. The turnip will become translucent and sweet, absorbing the herbal broth beautifully.
Lift out and discard the herb bundle or use a slotted spoon to remove loose herbs. Taste the broth β it should have a pleasant earthy bitterness overlaid with sweetness from the vegetables and savory depth from the meat. Add the salt gradually, tasting between additions. The broth should not taste heavily salted; the seasoning is a gentle background note.
If the bitterness feels too sharp, a pinch of sugar or a few drops of soy sauce rounds it out without masking the herbal quality.
Remove the pot from the heat and let it rest, uncovered, for 3β4 minutes. Any remaining fat will rise to the surface and can be skimmed off with a spoon for a lighter broth, or left in for a richer result. The brief resting period also allows the flavors to settle and integrate.
Ladle the broth, meat, and vegetables into deep bowls. The soup is traditionally served very hot, as the warmth is considered part of its restorative quality. Accompany with steamed rice on the side or enjoy the broth on its own as a restorative starter.
A small dish of sea salt and a few slices of fresh chili placed on the table let diners adjust seasoning to their own taste, which is the traditional way of serving.
Source dried herbs from a Chinese herbal medicine shop (zhong yao dian) rather than a general supermarket β the quality and potency of astragalus root, mugwort, and goji leaf varies enormously, and herbal shops stock material specifically intended for cooking and brewing rather than decorative purposes.
The soup should taste slightly bitter and earthy β this is not a flaw but the defining quality. Aboriginal Taiwanese cooks specifically select herbs for this characteristic, which is understood as the medicinal dimension of the dish. If your broth tastes flat and sweet with no bitterness, the herbs were either too old or added in insufficient quantity.
Do not overcook the root vegetables. Add carrots and turnip with about 12β15 minutes left in the cooking time so they soften without turning mushy. They should offer a little resistance to the bite and their natural color should remain bright rather than dull.
Blanching the protein in cold water first is non-negotiable for a clear broth. Skipping this step leaves grey foam in the soup that is difficult to skim out completely and gives the broth an off-flavor that competes with the herbs.
Make a double batch and freeze the broth in 2-cup portions. The herb-infused broth is an excellent base for congee, noodle soups, or braised vegetables throughout the week.
If you cannot find the specific dried herbs listed, a simple substitute blend of 1 tsp dried thyme, a few slices of fresh ginger, and a small handful of wolfberries (goji berries) will approximate the layered bitter-sweet-earthy profile of the original.
Mountain mushroom version: add 100 g of dried shiitake or wood ear mushrooms (soaked and rinsed) along with the herbs at the start β they deepen the broth's umami significantly and are particularly common in Bunun and Tsou highland cooking.
Fish broth version: replace pork or chicken with 300 g of firm white fish (grouper or sea bass work well) added in the final 8 minutes only, so it stays tender. This is the coastal Amis interpretation, which traditionally uses freshwater trout or eel caught from mountain streams.
Hearty noodle soup: cook 80 g of wide rice noodles or wheat noodles separately, then place them in the serving bowl and ladle the hot herb broth, meat, and vegetables over the top. This turns the soup into a complete one-bowl meal.
Fully vegetarian: omit the meat entirely and use a kombu or dried shiitake stock as the base liquid. Increase the herb quantity by about 50% to compensate for the missing savory depth from meat, and add a piece of tofu cut into 2 cm cubes in the final 5 minutes.
Slow cooker adaptation: combine blanched protein, soaked herbs, and root vegetables in a slow cooker with 6 cups of water. Cook on LOW for 4β5 hours. The long, low heat draws an extraordinarily deep flavor from the herbs without any risk of boiling the broth cloudy.
Cool the soup to room temperature within 2 hours of cooking, then refrigerate in a sealed container for up to 4 days. The flavors deepen overnight, making next-day soup arguably better than freshly made. To reheat, warm gently over medium-low heat until just simmering β do not boil, which toughens the meat. The soup also freezes well for up to 2 months; freeze the broth and vegetables together and thaw overnight in the refrigerator before reheating.
Wild herb soup traditions among Taiwan's indigenous peoples are documented in ethnographic records compiled by Japanese colonial anthropologists in the early twentieth century, who noted that mountain communities of the Atayal, Bunun, and Amis peoples regularly brewed medicinal broths from foraged botanicals as both daily nutrition and treatment for illness. The specific combination of mugwort, astragalus, and goji leaf reflects knowledge systems that predate written records and are believed to have developed over at least two thousand years of highland habitation. These traditions survived colonization and urbanization largely through oral transmission within families, and have experienced a cultural revival since the 1990s as part of a broader indigenous rights movement in Taiwan that reclaimed language, ceremony, and foodways.
Chinese herbal medicine shops (zhong yao dian) are the best source β look for dried mugwort (ai-cao), astragalus root slices (huang qi), and dried goji leaf (gou qi ye) sold loose by weight. In cities with a Taiwanese or Chinese community, these shops are common in older commercial districts. Online retailers such as Heng Fung Herbs or Mountain Rose Herbs carry astragalus and dried mugwort; search specifically for 'Taiwanese aboriginal herb soup mix' to find pre-assembled blends on platforms like Shopee Taiwan or iHerb.
Both things are true simultaneously. In traditional aboriginal Taiwanese medicine, the herbs in this soup are classified as immune-supporting, warming, and qi-tonifying. Modern pharmacological research supports several of these claims: astragalus root (Astragalus membranaceus) contains polysaccharides that have demonstrated immunomodulatory effects in clinical studies, and mugwort has well-documented anti-inflammatory compounds. That said, this is primarily a nourishing, deeply flavorful soup rather than a pharmaceutical preparation β think of the medicinal dimension as a meaningful bonus built into a genuinely delicious dish.
The most common cause is using too much mugwort relative to the other herbs, or simmering it longer than recommended. Mugwort becomes increasingly bitter the longer it cooks, so if your blend is heavy on mugwort, reduce the simmer time to 10 minutes and taste before going further. You can also balance pronounced bitterness with a pinch of sugar, a splash of rice wine, or a few drops of light soy sauce β these don't mask the herbal character but round off the sharp edge.
Yes, and it is actually better the next day. The herb infusion continues as the soup sits and the flavor becomes more rounded and integrated overnight. Prepare the complete soup, cool it quickly, and refrigerate. When reheating, warm it slowly over medium-low heat to just below a simmer rather than bringing it back to a boil, which can make the meat fibrous and cause the vegetables to fall apart.
Astragalus root is the hardest to substitute because it provides a distinctive mild sweetness and body to the broth; in a pinch, a few thin slices of fresh ginger plus a small piece of dried tangerine peel create a similar warming-sweet base note. Goji leaf can be replaced with fresh spinach or watercress added in the final 2 minutes β they won't have the same bitter complexity, but they keep the soup nutritious and green. The overall character of the dish will be gentler without the specific aboriginal mountain herbs, but still deeply satisfying.
