Natural Healing — Algodoncillos

Algodoncillos (Asclepias spp.)

There are approximately 200 species of Asclepias worldwide, 75 of which are found in Mexico, and at least 17 of those have reported medicinal uses. The plants in this genus are most often referred to as algodoncillos, talayotes, or venenillos in general, although some varieties are known by other names by local populations. Unfortunately, as is common with plant names in Mexico, many of the names are also used to identify unrelated plants, making positive identification difficult. 

Most Asclepias are toxic, although certain varieties are used medicinally, and others are essential to the lifecycle of the monarch butterfly. A few have edible fruit or leaves.

Inmortal (Asclepias asperula)

Asclepias asperula ssp. Asperula is known as antelope horns or spider milkweed in English and algodoncillo and cuerno de antílope in addition to inmortal in Spanish. Bernardino de Sahagún reported that inmortal was used as a laxative by the Aztecs. An Aztec Herbal: The Classic Codex of 1552 included it in a chest congestion remedy as well. 

As a tonic, laxative, or expectorant, a teaspoon of powdered root is added to a glass of water first thing in the morning. The root powder is also used in a tincture to bring on menstruation. A stronger dose is employed to strengthen labor pains and quicken delivery. Additionally, the ground root is soaked in water and rubbed on the laboring mother’s abdomen. As an aid to expel the placenta, a tea is made from inmortal ground root and epazote leaves (Dysphania ambrosioides).

Asclepias asperula is a favorite of monarch butterfly caterpillars. It contains cardiac glycosides, which are toxic. The butterfly retains this toxicity, making them poisonous to predators. Inmortal is toxic to humans and livestock as well, and extreme care should be exercised when employing this plant for any remedy. 

Asclepias asperula ssp. Capricornu is a second subspecies of Asclepias asperula also known by the name inmortal. The leaves of the capricornu are broader, and the floral crowns are whiter than subspecies asperula. Accepted synonyms for Asclepias asperula ssp. Capricornu include Asclepias asperula var. Decumbens, Asclepias capricornu, Asclepias capricornu ssp. Occidentalis, Asclepias decumbens, Asclepiodora decumbens, and Aceratos asperula. Asclepias asperula ssp. Capricornu is prescribed in some areas as an abortifacient.

Quiebra muelas (Asclepias curassavica)

Asclepias curassavica has a whole host of names including flor de sangre, burladora, mata ganado, cancerillo or cancerina, cresta de gallo, and quiebra muelas. Indigenous names include pameyat warnal (Tzeltal), xpamal yat (tzotzil), tesuchi-potei (otomí), chac anal or x-anal (Maya), and punchix huítz (Tenek).

Throughout Mexico, the latex sap is most often prescribed for tooth problems, especially as pain relief from cavities or during tooth extraction. In the state of Tabasco, the plant’s seed is placed on the painful tooth. Asclepias curassavica has been shown to be anti-inflammatory and possess an antinociceptive effect.

In other areas, the sap is applied to the skin for various ailments such as acne, gonorrhea, warts, cold sores, and erysipelas (bacterial skin infections). Pus-filled sores are covered in a poultice of crushed leaves. Bacterial skin infections call for 25 to 30 ground leaves made into a paste with a little salt water and applied three or four times daily for two days. Leaves boiled with salt and added to a bath for a pimple treatment. 

In the state of Puebla, an acne decoction employed as a wash is made with quieba muelas, flor tocada (Lobelia laxiflora), and gobernadora (Lantana camara). Also, in Puebla, snake bites, scorpion stings, and embedded thorns are treated with a quiebra muelas plant decoction. A wound wash is made by boiling the branches and leaves from quiebra muelas, epazote (Dysphania ambrosioides), escoba amargosa (Parthenium hysterophorus), and salt. 

The flowers are made into a tincture for headaches and rheumatism relief. Pain in the spleen is treated with half a glass of water and four drops of latex drunk several times a day. A root decoction is prescribed for painful urination. 

Quiebra muelas is used as an anti-parastic compouns and purgative. It’s recommended for bilis (rage). It’s considered a “hot” plant.

Asclepias curassavica demonstrates antioxidant, antitumor, cytotoxic, and pro-apoptotic activity, making it useful in cancer treatments. 

As a respiratory aid for congestion from colds and flu, the latex is liberally applied to a cotton cloth, allowed to dry, and then sniffed, which causes sneezing, in effect clearing out the nasal passages temporarily. One study has suggested quiebra muelas is effective in treating COVID-19 as it increases respiratory capacity and reduces symptoms.

Asclepias notha and Asclepias lanuginosa are considered botanical synonyms. Other names for the hierba de chicle include hierba de leche, ita kutu, and chicle guizh guts in Zapotec. The sap is used to made chicle (chewing gum) by the Chocho, a Mixtec group in Oaxaca.

Echoes of History

Every morning when I read through the headlines, I become more and more concerned about the direction the US is heading and wonder how the new authoritarian regime will affect my life in Mexico and my loved ones’ lives still in the US. Doing a little historical digging, here are some of the things that concern me most.

Cracks in the Democratic Foundation

Recent analysis describes the U.S. displaying disturbing similarities to Weimar Germany: political polarization, declining institutional trust, extremist rhetoric, socioeconomic anger, and media fragmentation may be pushing democratic erosion, or worse. 

Stanford democracy scholar Larry Diamond sees an accelerating global decline in democratic norms, with slow authoritarian creep in many nations, including the U.S., often underpinned by inequality and disinformation. 

Personal Powerusurpation and Legal Erosion

The pattern of executive overreach in America mirrors pre-WWII Germany. Both invoke “emergency” powers to skirt democratic checks. In Germany, the Reichstag Fire Decree and Enabling Act dismantled civil liberties and legislative authority. In the U.S., critics point to an uptick in executive rulings, including invoking obscure laws to detain or deport without full due process. 

Another hallmark of rising authoritarianism is institutional capture, where courts, law enforcement, and agencies are stacked with political loyalists. The U.S. has seen growing politicization of the judiciary and federal agencies, echoing Germany’s purge of independent institutions. 

Scapegoating, Propaganda, and Cults of Personality

Scapegoating has long been a potent tool for authoritarian regimes, used to unify a majority by targeting marginalized groups. In 1930s Nazi Germany, Jewish people, communists, Roma, and others were falsely blamed for Germany’s troubles and were framed as existential threats to the “Volksgemeinschaft.” Today in the U.S., similar patterns emerge: immigrants, asylum seekers, and religious or racial minorities are increasingly portrayed as threats to national identity or security.

This narrative is reinforced by a vast network of ICE detention centers, now resembling a modern internment system. In 2025, internal planning documents reveal ICE’s intention to nearly double its inmate capacity from 50,000 to over 107,000, which involved adding 125 facilities, including mega-detention and soft-sided “tent” structures, with major private prison contractors like Geo Group and CoreCivic set to profit massively.

First-hand reports reinforce these concerns. Many facilities are described as overcrowded, unsanitary, and neglectful, with detainees forced to sleep on concrete floors, lacking adequate food, water, or medical care. In a harrowing account, a detainee likened conditions to something worse than prison, describing moldy cells and denial of basic needs, while lawmakers seeking oversight have repeatedly been blocked from entering these centers.

The expansion of these detention systems echoes the Japanese American internment camps of World War II. During that era, over 120,000 U.S. citizens and residents of Japanese descent were forcibly relocated and incarcerated without due process, which was justified under wartime hysteria and xenophobia, and later condemned as a grave constitutional violation. Today, the toll of expanding ICE custody, including detaining non-criminal individuals and asylum seekers, is strikingly similar. One report notes that the proposed doubling in detainees would bring numbers “close to the number of Japanese Americans kept in internment camps”.

Beyond physical repression, propaganda plays a crucial role in normalizing such abuses. Just as Nazi Germany used state media and mass rallies to build cults of personality around Hitler, modern political media in the U.S. idolize certain political figures and delegitimize dissent. This framing enables the gradual erosion of democratic norms, painting detention centers as necessary for security, rather than as sites of human rights violations.

All this underscores a brutal truth: once a society normalizes the detention of “undesirable” groups under the guise of security, it erodes the very foundations of rights and protections for all. The U.S. risks repeating historical mistakes unless public scrutiny, media vigilance, and legal oversight intervene.

What This Means for Me as an Expat in Mexico

Mexico as a Historical Haven but Not a Utopian Escape

For decades, Mexico has provided refuge for Americans fleeing political repression and ideological persecution. From anti-war activists of the 1960s–70s to self-exiled journalists, Mexico has been a sanctuary and, increasingly, a destination for U.S. expatriates seeking relative safety or an affordable life. As of 2022, there are an estimated 1.6 million Americans living in Mexico, including retirees, digital nomads, students, and families.

Still, Mexico, while historically hospitable, is not without its challenges. A Los Angeles Times column notes that affluent American expats may unintentionally insulate themselves from local realities, living in privileged bubbles that shield them from poverty, violence, or corruption. “Expats are immune to that… playing the game of life on someone else’s server with cheat codes.”

A major flashpoint has been the sudden rise in anti-gentrification protests in Mexico City’s trendy neighborhoods like Roma and Condesa. In early July 2025, residents marched through long-time urban communities facing skyrocketing rents and cultural displacement triggered by foreign arrivals, often labeled as “digital nomads.” Protesters carried signs reading “Gringo: Stop stealing our home” and “Housing to live in, not to invest in!” criticizing both Airbnb-driven short-term rentals and government-promoted tourism strategies.

Furthermore, Mexico faces its own authoritarian pressures: centralization of political power, weakening of institutions, and militarization of governance. Some analysts argue the country may be drifting toward “competitive authoritarianism.” Executive overreach, judicial reforms, and suppression of dissent muddy the promise of stability for longtime dissidents.

Moreover, political violence, particularly assassinations connected to organized crime targeting candidates, continues to threaten democracy at the local level, complicating political life for both citizens and exiles.

Final Thoughts

Living in Mexico, I’ve crafted a life I genuinely enjoy, built on community, cultural richness, and personal freedom. Despite the challenges, this country has become a place I call home. 

Yet, I can’t ignore that the political climate is shifting here as well. Mexico has increasingly shown a willingness to kowtow to U.S. pressure in politically sensitive areas, a dynamic that could strain its autonomy and indirectly affect those of us who have built our lives here.

  • In August 2025, Mexico extradited 26 alleged cartel members to the U.S., a move many analysts regard less as a sovereign governmental decision and more as a maneuver to appease U.S. leadership and stave off economic sanctions tied to the fentanyl crisis. This bypassed the typical judicial process, suggesting the extraditions were influenced by Washington’s pressure.
  • Earlier this year, Mexico deployed 10,000 National Guard troops along the northern border under Operation Frontera Norte, directly responding to U.S. threats of tariffs linked to migration control, which was a decision seen by critics as reactive compliance rather than proactive defense of national sovereignty.
  • Most notably, Mexico is now pursuing constitutional reforms to explicitly protect against possible U.S. military incursions or interventions, an ominous signal that such threats feel plausible enough to require legal reinforcement.

Whether democracy will crack, stabilize, or rebound is unpredictable, making my life in Mexico feel even more precious and fragile. It’s not perfect, but it might be all there is before too long.

Natural Healing — Zarzaparrilla

Photo credit: makamuki0

Color me surprised when I discovered the Maya her Koh-key (also spelled koke’) was good old fashioned sarsaparilla and a Mexican native plant to boot. Zarzaparrilla is the Spanish term for the Nahuatl herb, Mecapàtli, heralded by Nicolás Monardes in his book Joyfull Newes Out of the Newfound World (1574) in two entire chapters. He recorded information about a tonic from zarzaparrilla root drunk three times daily for two weeks to sweat out illness. Unsurprisingly, both the “sweat it out” cure and zarzaparrilla root juice is found in traditional Mexican remedies today.

Other names include kgentsililh in Totonac, t’ocnal ts’aah in Huastec, bejuco de canasta (also Philodendron longirrhizum), olcacatzin, zarza parra, cabrestillo, alambrillo, diente de perro, uarhocutaracu sapichu in Purepecha, and cocolmeca, although this term is more often employed to refer to Dioscorea mexicana.

Although there may be as many as 350 worldwide species of this plant, the word zarzaparrilla generally indicates one of five varieties of Smilax used medicinally in Mexico; Smilax spinosa, Smilax domingensis, Smilax ornata, Smilax aristolochiifolia, Smilax moranensis. The rhizome from these plants is used interchangeably in remedies for stomach problems, menstrual disorders, adult-onset diabetes, syphilis, rheumatism, blood disorders, skin inflammations, and diarrhea. 

During childbirth, a decoction made with three fingers of zarzaparilla root and nine thorns from the plant, epazote, sweetened with melipona honey is given to the laboring mother. Although I haven’t seen any studies suggesting zarzaparilla causes uterine contractions, it does have analgesic properties.  

As a blood fortifying tonic, an infusion is made with 80 grams of the zarzaparrilla rhizome for each half liter of water. The root should be soaked for at least 12 hours and then boiled in the same water. Drink three cups daily. Smilax aristolochiaefolia has been shown to aid in the formation of blood cellular components in cases of aplastic anemia, while other varieties of Smilax have demonstrated high anti-hemolytic activity, supporting the traditional use as a blood-fortifier.

For rheumatism, two spoonfuls of chopped zarzaparrilla root (Smilax ornata) and three spoonfuls of chopped cola de caballo (Equisetum hyemale) are boiled in one liter of water for ten minutes. The infusion is covered. Strain and drink every two hours. Studies have shown that Smilax ornata contains significant analgesic and anti-inflammatory properties.

Smilax spinosa is an effective treatment for male impotency because of the estrogenic properties it contains. An infusion for male impotency is made from 1 tablespoon of ground zarzaparrilla root in one liter of boiling water. Allow it to cool, strain, and drink three times a day about 30 minutes before meals. 

For menopausal symptoms, try traditional cerveza de raíz (root beer). Add 7 grams of zarzaparrilla root (Smilax ornata), 1 finger-sized piece of jengibre (Zingiber officinale) cut into pieces but not peeled, 1 vainilla (vanilla planifolia) beanpod (already opened) or two teaspoons of vanilla extract, and two star anise (Illicium verum) pods to four liters of water and bring it to a boil. Turn down the heat and add seven cups of honey. Stir until it dissolves. Strain and allow it to cool. To serve, add two or three tablespoons to a glass of mineral water. Stir and enjoy.

Smilax domingensis is an estrogen agonists, found to be useful in osteoporosis and breast cancer prevention. Smilax spinosa root demonstrates anti-neoplastic effects against breast cancer cells.

Smilax ornata is used to treat ringworm infections in some areas of Guatemala and Mexico. Studies have shown that it has fungicidal and fungistatic activities supporting this traditional use. Smilax ornata root also exhibits antifungal activity and has been shown to be useful in the treatment of yeast infections. 

One syphilis treatment calls for zarzaparrilla root (Smilax aristolochiifolia /Smilax morenensis) and the bark of guayacán de América (Guaiacum sanctum). The two are boiled for two minutes and steeped for 10 minutes before straining. It should be drunk in small doses throughout the day. Smilax spinosa has antioxidative, antibacterial, antiprotozoal, and anti-microbial activities. 

As syphilis is a bacterial infection, zarzaparilla’s antibacterial and anti-inflammatory properties are beneficial in treating this and other genital infections. 

A daily tonic infusion for adult-onset diabetes is made with 1 liter of water and 2 grams of zarzaparrilla root boiled for 15 minutes. Strain and drink hot or cold. Smilax moranensis is a α-glucosidase inhibitor, Smilax aristolochiifolia has a proven hypoglycemic effect, and Smilax moranensis inhibits hepatic glucose production, supporting the traditional use for the treatment of diabetes type-2.  

Smilax aristolochiifolia root has been shown to counteract some symptoms of metabolic syndrome, a cluster of conditions that increase the risk of heart disease, stroke, and diabetes, including high blood pressure, high blood sugar, excess body fat around the waist and abnormal cholesterol levels. Studies have shown that the Smilax species are excellent sources of anti-tumor compounds as well. 

El popo is a traditional celebratory beverage that contains zarzaparilla stems found in Veracruz and Oaxaca. It also has pulverized cacao (Theobroma cacao), piloncillo (coned brown sugar), canela (Cinnamomum zeylanicum), anís (Pimpinella anisum), and whole rice.
