Understanding Chemo
Chemo is an indigenous hot beverage prepared from coffee leaves and traditionally consumed in Tepi Town, southwestern Ethiopia. Although widely embedded in everyday life and local food traditions, it has remained largely undocumented in academic literature until now.
Core Preparation: Coffee leaves from Coffea arabica are roasted, heated, or boiled and combined with locally available aromatic herbs and spices including Ocimum basilicum, Lippia adoensis, Zingiber officinale, and Capsicum frutescens. The leaves themselves are tough and fibrous and are strained out before serving. The result is a dark, semi-solid infusion served hot, often accompanied by starchy foods.
Cultural Significance: Chemo serves as a key expression of hospitality, shared during communal activities, religious ceremonies, and daily social interactions. Women are the primary custodians of preparation knowledge, transmitting skills through observation and practice across generations. The beverage reflects locally adapted strategies of resource use—by utilizing renewable coffee leaves rather than beans, it does not compete with market-oriented coffee production.
Three Documented Methods: The ethnobotanical research identified three main preparation methods practiced in Tepi Town, each producing distinct sensory characteristics. This compendium presents all three documented methods, plus a hypothetical minimal version for reference.
About This Research
This recipe compendium is based on a mixed-methods ethnobotanical study conducted from August to October 2025 in Tepi Town, Sheka Zone. Data were collected from 64 households and 16 key informants using semi-structured interviews, participant observation, focus group discussions, and botanical specimen collection. All participants provided informed consent, and ethical approval was obtained from the Tepi Town Administration.
The study documents traditional preparation methods, ingredient composition, cultural significance, gender roles in knowledge transmission, and challenges related to ingredient availability and market access. It provides ethnographic evidence of Chemo's continued relevance while acknowledging that further research integrating chemical analysis, standardized socio-economic data, and comparative perspectives is needed.
Method 1: Roasted Leaf Preparation
Most Widely Practiced in Tepi Town
Light roasting of coffee leaves produces a sweeter, more balanced flavor. This method was described as "widely adopted" by participants and is the most common preparation approach documented in households across all eight study sites.

Preparation Steps
đź“Ś Method Notes
This recipe reflects the most widely practiced method documented in Tepi Town. The proportions are based on the study's measured averages for one liter of water. Participants frequently described this method as producing "a sweeter and more balanced flavor," which may explain its widespread adoption.
Ingredient proportions can be adjusted based on local availability and household taste preference—there is flexibility within the tradition. The coffee leaves are tough and fibrous; they are strained out before serving and not consumed.
Method 2: Heated Leaf Preparation
Milder, More Delicate Approach
Coffee leaves are briefly heated (not roasted) for approximately 5 minutes while kept moist. This produces a milder taste and lighter aroma compared to the roasted method, preferred by those seeking a more subtle, refreshing beverage.

đź“Ś Method Notes
Critical Difference: Instead of roasting, the coffee leaves are briefly heated over fire for approximately 5 minutes and crushed while still moist. This is a deliberate and subtle distinction that produces noticeably different sensory characteristics.
The paper notes that this approach produces "a milder taste and a lighter aroma compared to the roasted-leaf method." All other ingredients and proportions remain consistent with Method 1.
Method 3: Majang Ethnic Tradition
Separate Preparation with Customizable Chili
Practiced primarily among the Majang ethnic group, this method involves boiling coffee leaves and chili separately, then combining them at serving time. This allows individual customization of heat and medicinal potency based on personal preference and perceived need.

Medicinal Customization: The paper notes that "larger quantities of chili are often added for individuals experiencing colds or respiratory discomfort, reflecting locally perceived medicinal properties rather than standardized therapeutic dosing."
This method uniquely allows adjustment at serving time, making it responsive to individual health needs and preferences. It reflects an adaptive, individualized approach characteristic of traditional knowledge systems where therapy is context-dependent rather than formulaic.
Hypothetical Minimal Method
Extrapolation (Not Documented in Research)
⚠️ Important Disclaimer
This recipe is NOT documented in the ethnobotanical research. It represents a hypothetical extrapolation based on core ingredients present across all documented methods. The research does not describe any household in Tepi Town preparing Chemo without aromatic herbs and spices.
All 64 households surveyed added "a range of locally available herbs and spices." This minimal version is presented for informational purposes only, to illustrate what an absolute baseline preparation might theoretically be if aromatic ingredients became unavailable. It should not be considered an authentic or traditional Chemo preparation.

đź“Ś Research Reality
The study explicitly states: "The selection and combination of these plants varied across households and sites, reflecting local taste preferences and cultural practices." The variation documented is in proportions and leaf treatment, never in the presence or absence of aromatic herbs and spices.
For authentic, documented Chemo preparations, refer to Methods 1, 2, or 3.
