Why does my throat itch after eating yams?

Why Does Elephant Yam Cause Itching? – Why Do Yam Itch And How To Cook Them The Yam peels contains calcium oxalate / saponins juice when comes in contact with the skin starts to itch. This is known as Contact Dermatitis. It causes redness and itching for some time and is irritating. The peels from Elephant foot yam contains tiny crystals of calcium oxalate and saponins.

• Firstly before you peel the yam, make sure you don’t wash them, because when you wash them the juice will flow in while cutting and cause itchiness. Thus do not wash them.
• You can use a rubber gloves while cutting them.
• Apply Coconut oil in your hands before cutting.
• Baking the yam helps to peel the skin faster.

By mistake if the juice falls in your hands, you can apply the red palm oil or peppermint oil immediately to stop the itching.

Why are yams itchy?

Abstract – This study was designed to investigate whether or not the areas of the human body most sensitive to itch stimuli are identical with the body parts least sensitive to tactual discrimination, a hypothesis which arouse from our previous studies of itching.

• Subjects were 12 college students (six males and six females).
• The itching was induced by grated Japanese yam.
• The body areas were the upper arm (with large two-point thresholds), the lower leg (with intermediate two-point thresholds), and the middle finger (with small two-point thresholds).
• An experimental session consisted of a stimulus-application period (200 s), and a post-application period (600 s) during which the itching increases markedly.

(After wiping off the grated yam, itching is increased because of the needle-crystals of calcium oxalate contained in the yam peel which penetrate slightly into the skin in the process of wiping.) Self-ratings on itching and the volume of dermal blood flow were recorded during two periods.

Are yams high in histamine?

Is yam high in histamine? Yam is likely suitable for a low histamine diet. Yam is likely low in histamine and other amines and does not trigger release of the body’s natural histamine. Every person has unique dietary triggers. Your reaction to yam may be different than someone else’s. Test your individual tolerance to ingredients carefully and then keep track of them with the, Check if ingredients like yam are histamine-friendly instantly with Fig. Scan a product’s barcode and the Fig App will highlight ingredients that may be high in histamine. If a product isn’t suitable, Fig will recommend low histamine alternatives. When you avoid hundreds of ingredients, grocery shopping is a challenge. The Low Histamine diet helps reduce symptoms from conditions like Histamine Intolerance (HIT) and Mast Cell Activation Syndrome (MCAS). The diet is challenging to follow, as there are very few primary data sources available that accurately detail which ingredients are: 1.) High in histamine and other amines like tyramine 2.) Histamine liberators (ingredients that trigger release of the body’s natural histamine) 3.) DAO blockers (ingredients that block DAO, the enzyme that breaks down histamine and other amines) We’ve done our best to provide accurate information on the histamine content of yam; however, we suggest working with a dietitian to navigate the diet and understand your individual needs.

1. Eep in mind that multiple histamine food lists exist.
2. Some of them are based on science, and some of them are based on patient experiences.
3. Use these lists as a starting place for your own personalized list of food triggers.
4. You know your body best! Check the for the latest ingredient annotations.

Yam ( Dioscorea opposita ) is commonly consumed in East Asia, but allergic reaction to this plant food is rare. To date, there is no report of anaphylactic reaction after ingestion of cooked yam. We described 3 cases with anaphylaxis after eating boiled yam and 1 present with oral allergy syndrome as well.

1. Basophil activation test in patients showed positive reactivity to boiled yam extract.
2. In immunoblotting, a 30-kDa protein was recognized by all patients’ sera and a 17-kDa band was detected by 1 patient.
3. N-terminal amino acid revealed the 30-kDa IgE reacted band was DB3S, dioscorin in Dioscorea tuber.

It promoted us that DB3S was a thermal stable oral allergen to trigger anaphylactic reaction and oral allergy syndrome in cooked yam ( D. opposita ) allergy. Patients with this plant food allergy should avoid both raw and well-cooked yam. Keywords: Anaphylaxis, DB3S, Dioscorea opposite, Thermal stable allergen, Yam Yam is the common name for the tuber of Dioscorea opposita,D.

1. Opposita belongs to the Dioscoreaceae family, Dioscorea genus.
2. It is wildly consumed in East Asia and also serves as an important material medicine,
3. As a common food, it is usually cooked by boiling or steaming, but rarely eaten crawly.
4. Yam is mainly composed of carbohydrate, whereas it also contains 8% protein,

Allergic reaction to yam is rare in both clinics and literature. To our best knowledge, it has been only reported in patients with allergic symptom after inhaling or eating raw yam, However, allergic reactions to cooked yam have never been published. Here, we represented 3 anaphylactic cases due to digestion boiled yam and detected the candidate allergen in cooked yam.

• Three patients experienced anaphylaxis and oral allergy symptom (OAS) within 30 minutes after ingestion of boiled yam.
• All of them had a comorbidity of mugwort pollinosis.
• The detailed clinical data was summarized in,
• Considering of anaphylactic history, we did not preform skin prick test and double blind placebo control oral challenge test.

Patients’ information

Patients’ No.	Sex	Age (yr)	Episodes of OAS	Episodes of anaphylaxis	Interval * (min)	Symptoms of anaphylaxis
1	Male	19		3	30	Generalized urticaria, chest tightness, dyspnea, hypotension, and collapse
2	Male	53	Several times	Several times	10	Tongue and laryngeal edema, itchy eyes and palms, labored breath
3	Male	43		1	15–20	Similar to patient 1

Basophil activation test was analyzed by the Flow CAST kit (BÜHLMANN, Schönenbuch, Switzerland). After signed an informed consent, 2-mL ethylenediaminetetraacetic acid anticoagulated peripheral blood and 2-mL sera were collected from 3 patients and 3 nonatopic adults.D. opposite (yam) was peeled, then boiled for 30 minutes and mashed, prepared in distilled water (1: 10 w/v) and collected the supernatant. According to the manufacture’s protocol, after coincubation with whole peripheral blood and boiled yam extract (0.25, 0.50, and 0.75 mg/mL), CD63 expression on the surface of activated basophil was determined by flow cytometry. For food allergen, activation percentage ≥15% was defined as positive. In patients 1, 2, and 3, 63.24%, 75.64%, and 24.07% of basophil were detected as activation (shown in ), whereas the controls’ sera showed negative activation of basophil (<2%). (A) Basophil activation test. The rate of active basophil expressing CD63 in patients 1, 2, and 3 was 63.24%, 75.64%, and 24.07%. P1, 2, and 3: patient 1, 2 and 3. (B) Separation on 4%–12% sodium dodecyl sulfate-polyacrylamide gel electrophoresis and analysis of immunoblot. Lane 1 was protein marker. With Coomassie brilliant blue stain, more than 11 bands were observed in the total extract of boiled yam (lane 2). Immunoblot with sera from patients 1, 2, and 3 (lanes 3, 4, and 5) detected a 30-kDa IgE binding band. A 17-kDa protein was recognized by patient 3 (lane 5). The boiled yam extract was separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and more than 11 bands ranging from 10 to 130 kDa were observed. By the immunoblotting, a protein band with molecular mass around 30 kDa was recognized by all the patients' sera (), but by none of the nonatopic controls. In addition, sera from patient 3 also reacted with a 17-kDa band. No immunoreactive bands were detected by controls' sera. The 13-base N-terminal amino acid of the 30-kDa protein band was identified as Val-Glu-Asp-Glu-Phe-Ser-Tyr-Ile-Glu-Gly-Asn-Pro-His. These amino acids displayed 100% identity with DB3S, tuber storage protein in Dioscorea tuber. Previous cases have been published as being allergic to raw yam. For instance, a case manifested as occupational asthma and rhinitis following inhalation of yam, one developed urticaria and angioedema due to ingestion of fresh yam powder and the other presented with dyspnea after exposure to yam dust, However, cooked yam has never been reported to cause allergic reactions. Here, we presented 3 anaphylactic cases due to boiled yam. In our patients, basophiles showed high reactivity to boiled yam extract, which confirmed the diagnosis. A 30-kDa IgE binding protein was determined by immunoblotting and indentified as DB3S by N-terminal amino acid sequencing. DB3S is a 30.46-kDa nonglycoprotein and composed of 268 amino acid residues (UniProtKB - ). It is a kind of dioscorin, the main storage protein in Dioscorea tuber, DB3S has been verified as inhaled and oral allergen in raw yam, Our study proofed that it was also a thermal stable oral allergen in cooked yam and could precipitated OAS and anaphylaxis. Therefore, patients with yam allergy should be educated not to take ingestion of raw nor well-cooked yam.
