TYPHACEAE

(Reedmace family)

This is a family of 10-12 species of aquatic and marsh herbs in one widely distributed genus (Mabberley 1987).

Calcium oxalate needle crystals (raphides) are known to occur in at least two species -T. angustifolia; T. latifolia (Prychid & Rudall 1999); according to Aplin (1981), this represents a dermatological hazard. Also, the abundantly-produced pollen, which may become airborne (Wodehouse 1971), is used in Chinese traditional medicine as a haemostat.

Typha angustifolia L.

[syn. Typha basedowii Graebner]

Narrow-leaved Cat-tail

According to Nadkarni (1976), the woolly soft inflorescence of T. angustifolia is used like cotton wool (see Gossypium L.) as a local dressing to wounds and ulcers. By his reference to the common name "elephant grass", Nadkarni (1976) may actually have been referring to Typha elephantina Roxb., an Indian species.

Typha capensis Rohrb.

Quisumbing (1951) records that the woolly inflorescence is used in the Philippines for healing wounds, probably acting as a mechanical haemostatic. The root and lower stem is used in the Eastern Cape, South Africa to prepare an infusion for use as an external wash for wounds (Grierson & Afolayan 1999).

Typha latifolia L.

Great Reedmace, Reedmace, False Bulrush, Bulrush, Cat's Tail, Cat-tail Flag, Broad-leaved Cat-tail

American Herbal Pharmacology Delegation (1975) reported that the dried and cooked pollen of this species acts as a blood coagulant - see also Typha orientalis below.

A widespread papular eruption occurred in workers who contacted the plant. The bites of Chilacis typhae were incriminated on circumstantial evidence (Balogh 1965).

Typha orientalis C.Presl

[syn. Typha muelleri Rohrb.]

Broad-leaved Cumbungi, Broad-leaved Bulrush

pu huang, the dried pollen from this species and also from T. angustifolia L., is recognised in Chinese traditional medicine as a haemostat (Huang 1993).
